Yamai Lunch Time

September 1st. The second day of school after the summer break.

In the scene of uproar of the lunch break, Shidou is walking down the stairs next to his classroom.

"Kuku… be honor, Shidou, to be able to present us Maiden of Cyclones – Yamai with a food."

"Gratitude. Thank you for showing us the way."

The voices could be heard from Shidou's back. Shidou let out a breath and glanced to that direction.

Two girls with the same face in a school uniform are there.

The slender girl who tied her hair up is throwing her head back and is laughing arrogantly, while another girl with a model-like figures who braided her hair up is bowing in a dazed looks.

Yamai Kaguya and Yamai Yuzuru. The twin spirits whose Shidou sealed off their powers two months ago.

"No, it is me who should apologize. It was because my miscommunication to begin with."

"Don't worry, I am being generous today; after all, I could be in the same class as Yuzuru. Yuzuru is too cute. If she is left alone, I don't know how many bad insects will come near her."

"Relief. Yuzuru is also relieved. Thinking that I must leave a super-beautiful girl such as Kaguya alone in a middle of a pack of wolves gave me shivers."

"No, fufu… Yuzuru is way cuter~"

"Disagreement. Kaguya is cuter."

"Aw you~, Yu~zu~ru~"

"Counterattack. Ka~gu~ya~"

Saying that, Kaguya and Yuzuru blushed and started to entwined each other's fingers. They are intimate enough that Shidou feel embarassed just by looking at them.

That is right. Yamai sisters are joining 3rd class of 2nd year of Raizen High School starting today.

Initially they have been considered to be transferred into the same 4th class as Shidou, however since their mental condition will stay stable enough if they are together, they ended up getting transferred into the next class instead.

Well, that is okay. Since these two had joined the school trip as transfer students who will be transferring into the school in the new semester, this is to be expected.

However, nobody has told Shidou the schedule until today.

As a result — Shidou couldn't prepared a boxed lunch for Yamai sisters.

That is why Shidou and both of them are going to the school store on the 1st floor.

"We are almost there —"

Shidou stopped at the familar-looking girl that appeared before him.

A doll-like girl with her hair cut around her shoulder fastened with a hairpin. The girl is holding a bread in a bag and a small milk carton in her hands.

"Oh, Origami. You are buying from school store today too?"

When Shidou asked, the girl — Tobiichi Origami nodded.

"Sometimes, when I am busy. Shidou too?"

"No, today is Kaguya's and Yuzuru's."

"I see."

Origami shortly answered and continued walking upstairs.

"Consent. If the store is Master Origami's favorite, then it might worth looking forward to."

Yuzuru nodded at Origami's back while seeing her off. Come to think of it, Yuzuru started calling Origami her master for some reason since the school trip.

"Well… it depends on which kind of bread."

Shidou walked down the stairs with a wry smile.

After walking for a short while — they can feel an abnormal air of excitement before them.

"Hmp? That is…?"

Kaguya who is walking behind Shidou said with a dubious voice.

That is not surprising. Among other things, numerous amount of students are gathering  in the first floor – in front of the school store as if it is a scene of year's end sales or rush hours in the morning.

"Croquette bread please! Also a strawberry milk!" "Ew, don't pull my clothes!" "Listen! The only good curry bread is the one that I eat!" "I must get it no matter what!" "Medic! Mediiiiiiiiic!" "Dammit, just only for a bread, why!?"

The crowds clamored. Screams could be heard. Shrieks are deafening everyone's ears.

The fierce scene of battlefield appeared over there from the unbalanceness of one store lady handling numerous amount of students.

"Ew, as I thought, it was too late. Looks like we have to wait a little before we can buy."

Shidou scratched his head and mumbled.

Although Shidou have used the school store for quite some times during his first year, the scene of battlefield was always there when he failed the sprint.

However, Kaguya and Yuzuru only lifted the corners of their lips at the scene of battlefield in front of the school store.

"What, what. This really gets me worked up. And when I thought they all are just a livestock without any fangs, seems like they still have a fighting instinct within them after all. Kuku, this boiled up my blood, Yuzuru?"

"Excitement. Not bad. While the past two months are comfortable, my body were getting rusty at it."

Kaguya and Yuzuru looked at each other and stepped forward.

"H-hey, you two."

"Don't worry, Shidou. I just have to pay to that store owner inside the store, don't I?"

"Agreement. Then that is easy. For Yuzuru and Kaguya, there is nothing impossible."

Said that, Kaguya and Yuzuru then started running out in the same moment.

When they reached the outer edge of the students, Yuzuru bend down one of her knee and clasped her hands.

"Setup. — Kaguya."

"Aw right!"

Kaguya shouted and mounted her legs on Yuzuru's hands. Incidentally, the slippers Kaguya was wearing are already thrown to the back without anyone realizing.

"Haaaaa!"

With the shouting, Kaguya's body is dancing in the air.

She then leaped over other student's heads and made a curve to the front of school store.

However—

"Secret Arts – 'Fallen Hero' Icarus Faaaaaall!!"

The moment such voice is heard from somewhere, someone fiercely blew Kaguya's body from the lefthand side with his body.

"Wha… ukyaa!?"

Kaguya shrieked and lose her balance mid-air.

She then fell quite a distance before her destination and engulfed into the pack of students.

"Gywaaaaa!?"

"Shiver. Kaguya!"

Yuzuru widen her eyes and called Kaguya's name.

And — as if they are responding to her voice, all students stopped moving all of sudden.

Yuzuru thought for a moment that the students are responding to her voice… but she was wrong.

The reason is known right away. The pungent smell is drifting from somewhere.

"W-what is this smell…"

The students knitted their eyebrows and pinched their nose. That is not surprising. The smell went through their nostril and induced them a nausea. If someone were to mix a garbage, a dead body of an animal, a waste water into moat's water in middle of summer then added it with a little bit of skunk's fart, it might smell like this. The shocking smell that could take away any appetite in a single breath.

Frightened at the smell, the students started covering their nose and mouth. While they are doing that, someone walked through them and finished the purchases at the school store.

Few moments later, the pungent smell disappeared. The students who have lost their appetite regained their appetite and started the scramble once again.

— Few minutes later.

"U… kyuuu…"

In front of school store that already became sparse, Kaguya, who had few footsteps printed on her back, made those miserable sounds while still lying down on the floor.

"Confirmation. Kaguya, are you okay?"

Yuzuru ran to her and lend her a hand. Kaguya took that hand and stood up staggerlingly. Even though it was only few minutes from earlier, she seemed worn-out for some reason.

"D-damn… what was that… did they do it because they knew I am the Maiden of Cyclones – Yamai Kaguya…!?"

Even though she said that, those words only echoed around vacantly. Kaguya grind her teeth and let out her breath.

"There is no choice… let's first feel our stomach and heal our body. Yuzuru, let's buy a bread."

"Agreement. Let's do it."

Kaguya walked staggeringly to the school store with Yuzuru supporting her.

However, their faces went gloom at the goods displayed on the shelf.

"Owner, don't you have something else?"

"Complaint. This is too horrible."

That is understandable. After all, on the shelf that is nearly completely hunted down, only two bags of bread crust remained. Even more, there is only a pack of jam left.

"I am sorry, but this is all?"

The store lady said with a calm voice as if the fierce scene of battle earlier never happened. The two frustrated for a short while but gave up in the end then paid the lady the money and slowly returned to Shidou.

However, on their ways.

A little girl ran from their side and bumped into them.

"Ugu!?"

"Caution. Who are you."

The two frown. The girl then raised up her head and started shaking her shoulders.

"I-I am sorry, I am in a hurry…"

Said that, the girl made a crying face.

Seeing the girl's weak looks, Yamai sisters then calmed down their irritation. They let out a breath and said "don't worry" while waving their hands at her.

The two is then back to where Shidou is. Shidou made a wry smile at them unconsciously.

"That was quite a disaster…"

"S-shut up! This is only an accident! Our true abilities are not like this!"

"Anger. As Kaguya said. I can't overlook any insult to Kaguya even if it was from Shidou."

"N-no, I didn't meant to insult her… Hey, wait, you two."

Shidou noticed something strange and pointed to their hands.

"Where did you put the breads you bought just now?"

"What?"

"Question. What do you mean?"

The two then inclined their head while looking at their own hands and twisted their face in fear.

That is not surprising. The bag of crust of the bread in their hand until now is reduced to just the tip of the bag they are holding with their finger.

"Wha… this is…"

"Puzzlement. Where is the bread…"

"— Fufu, fufufufu, fuhahahahaha!!"

While both two are looking around at their surroundings, the shrill laughter is heard from somewhere.

"W-who!?"

The moment Kaguya shouted, someone is seen jumping in front of her. The person placed his hands on the floor and made a forward roll followed by two somersault and landed in front of her.

The person is a tall man with a sharp eyes and his hair cut like a crest. For some reason his uniform is torn off at his shoulder and both of his arms are covered with bandage.  Furthermore, his waist is hanged with a bag of Yakisoba bread and a fruit-favored milk.

"Optimistic. How optimistic you are. Do you think you can use the school store with that level?"

"Huh…?"

While Shidou was still gaping at the situation, a man in white coat appeared from behind the pillar.  A scientist-looking slim man wearing a round glasses. In his hand there is a ham-egg sandwich and a coffee milk.

"Kukiki… well, let me welcome you. Welcome, new recruits, to our battlefield."

He said that and turned his coat. Inside his coat, several test tube with a cork could be seen hanging onto it.

When everyone is making a puzzled looks, another person again appeared from behind the pillar.

She is a girl with a plastic large bag on her back like a Santa Claus. Looking closer, the girl is the student who bumped into Yamai sisters earlier.

"Amazement. You are."

When Yuzuru said, the girl then made a scornful smile as if her weakly-looking earlier was a just made-up.

"Kyahaha — you won't be able to get any bread if you are like that."

Said that, the girl then took the crust of the bread out of her plastic bag and played with it on her hands.

"That is!"

"Stare. Yuzuru and Kaguya's bread crust."

Kaguya and Yuzuru gave them a hard stares and fixed their gazes them.

"Damn you, who are you?!"

When Kaguya shouted, those three put up a bold smile on their face.

"Hmp… then let us introduce ourselves!"

The man with crest-like haircut spread out his arms and lifted up his leg.

"Exceeding the mass with a flexible body and the legs that was harden from the gymnastic club. The noble of midair – 'Gonna Fly If You Blown It' <Aerial> Washitani Shunsuke! The 'Supreme Masterpiece' Favorite One is Yakisoba bread!"

"What is with that nickname. Also normally nobody said those stuff by themselves…

Shidou frown and narrowed his eyes.

However those three seems unconcerned. Next, the glassed man in white coat pushed his glasses then bend his body back taking a somewhat intelligent-looking pose.

"Misusing the science club's budget to create a fragrance that took away everyone's appetite! The scent of death – 'Stink Panic' <Professor> Karasuma Keiji. The 'Supreme Masterpiece' Favorite One is ham-egg sandwich."

"What a nuisance you are…"

And finally, the girl with the plastic bag on her back made a pose.

"Put others off-guard with that cute looks, then pickpocket the bread with lightning speed! The wizard of bewiderment – 'Oops I'm Sorry' <Pickpocket> Saginuma Ayumi! The 'Supreme Masterpiece' Favorite One is everything stole from others!"

"Isn't that a crime!"

"Kyahaha, don't underestimate me — check your pocket!"

"What?"

Heard that, Kaguya and Yuzuru then began searching their skirt's pocket.

"Huh… there is a money in it."

"Amazement. This is the price of the bread crust."

The threes purred their nose and gave signal to each other with their eyesight —

'— We are the Four Heavenly Kings of Raizen High School's school store!!'

They declared themselves in loud voice after taking a deep breath.

…For some reason, Shidou felt they could get along well with Yamai sisters (especially Kaguya).

"Four Heavenly Kings… you said?"

Kaguya said with a thrill voice. The threes then made a villain smile on their face.

"Fufu, exactly. The strongest warriors who conquered the school store of Raizen High School. That is us, Four Heavenly Kings!"

"Kukiki, that was some greetings for you new faces."

"Kyahaha, but~ if you are this weak  I don't think you should come anymore~?"

Four Heavenly Kings said and laughed. Yamai sisters then gave them a hard stares.

"Said what!? Are you trying to ridicule us Yamai, Maiden of Cyclones!?"

"Anger. I won't forgive any insults."

However, within that tense situation, Shidou only scratch his cheek.

Although there are few things on his mind, there is one important thing he wanted to say to them.

"You said Four Heavenly Kings… but there are only three of you."

However, this question seems to be within their expectations.

"Fufufu, 'that person' is the strongest of us. She don't usually make any appearance!"

"Right. Nicknamed 'Perfectionist' <Miss Perfect>. The person full of mystery who always got her hands on the bread without anybody realizing…"

"You who can't even defeat us is no match for that person —"

Four Heavenly Kings said in a ridicule tone. When though Shidou didn't feel anything, it was different for Yamai sisters. They grind their teeth in anger.

"Damn you, don't you think you can go back just fine. You have to repay with your life for making fun of us! Be stuck in the purgatory and regrets your doings!"

"Declaration. We can no longer overlooked your countless offense. We are asking you for a challenge."

However, the Four Heavenly Kings are still smiling with allowances even when they are exposed to the two's penetrating stares.

"Fu… the battle for today has already ended. Don't be such a bad loser."

"Kukiki, however, I like that spirits of yours. We are the strongest. Before us, nobody could get the bread they wanted."

"I am always open up for challenge~? Let's see, for the mean time…"

<Pickpocket> Saginuma looked at the calendar next to the store while saying that.

"Ara, what a good timing. The next Monday, there will be a limited bread. It is Rainbow Cream Bread for this month. How about… whoever is the first to get that will win~?"

Yamai sisters purred their nose and nodded at that sweet voice.

"Fine. The debt of the school store should be repay with the school store. I'll make you taste the taste of bread crust!"

"Declaration. I will make you regret your words."

Kaguya and Yuzuru pointed their fingers at them. After the three shrugged in pleasantness, they looked at Shidou with a mocking sight.

"Fu… seems like you've for some well-spirited pupil, 'No Reaction' <Dispel>."

"Kukiki, I heard you've fallen to the ignorant box lunch faction, but seems like you still have a pride of school store warrior left within you."

"But~ these girls won't be any match to us~?"

"What…?"

Shidou inclined his head at the unfamiliar nickname. However, there is no one else around him.

"M-me?"

"What are you saying. Of course, <Dispel>. One year ago, you easily escaped my mid-air attack, escaped Karasuma's death scent and escaped Saginuma's pickpocket — and able to get your Favorite One, Katsu Sandwich. You were such a strong warrior."

"Wait a minute, that is my first time hearing that."

Could not resist, Shidou raised his voice. Even though he used the school store quite few times during the first year and Katsu Sandwich was his favorite, he couldn't remembered that name.

"Are you saying you have already forgot the thrilling battle with us?"

"No, I mean…"

"Fu — it is fine if you want to play dumb."

"Kukiki, however your pupil seems to be in full spirits."

"Kyahaha, although it is a waste of time either way~"

Even though Shidou tried to hold them on, they won't listen to his story until the end. The Four Heavenly Kings made a villain laugh while walking off down the corridor.

Kaguya stared at them until they completely disappeared and stamp down on the floor.

"Damn! Making a fool of us! I'll let them see!"

"Agreement. I won't let they say the same the second time. — However, it is also the fact that Yuzuru and Kaguya lose. In order to clean up our names, a special training is required."

"Special training…"

Said that, Kaguya and Yuzuru looked at Shidou.

Shidou felt a sweat floating everywhere in his face at the bad feeling that went through his body.

◇

The next day. September 2nd. Saturday.

"Yawn…"

Shidou yawned. He is currently wearing a jersey with headband on his head and bamboo sword in his hand.

Of course, he did not dress like this because he wanted to.

Thanks to that nickname he don't know anything about, Shidou has been asked by Yamai sisters as the coach for their special training.

"Even though I thought the normal uniform is fine too…"

Shidou is currently in a hall surrounded by a gray wall. The virtual training space inside the mid-air ship <Fraxinas>.

By using the Realizer with equipments within the ship, it will allow them to recreate any kind of environments. Kotori offered them to use this room for the special training.

While Shidou is still trying hard to resist his drowsiness, two unique speaking voices could be heard.

"Kuku, how pitiful. I see you still can't escape from the spell of Hypnos."

"Greeting. Good morning."

Seems like Yamai sisters also arrived. Shidou looked the way the voices come from while rubbing his eyes —

"Right… Good mor — !?"

He froze for a split second.

After all, the uniform they both are currently wearing is the infamous near-extinct Bloomer-type gym clothes.

The label "Kaguya" and "Yuzuru" are written on their chest on their white uniform, under that is the Bloomer — the longing of all high school boys of the present age. Incidentally, while Kaguya left her shirt on top of the bloomer, Yuzuru tucked her shirt inside it.

"Hmp? I don't know why, but seems like you are now awake."

"Detection. Shidou's sight seems more intense than usual."

"Kaka. It means he is that spirited. Isn't that a good thing."

"Question. Is it that so."

Kaguya laughed broadly but Yuzuru inclined her head. Shidou averted his awoke eyes from them and continued.

"You two, what is with that uniform…"

"Ah, this one? Kotori prepared them for us. From what I heard, it seems to be the traditional training uniform of this country."

"Evaluation. It is really easy to move in this cloth. I especially like the mobility of the legs."

"…Is that so."

Shidou scratched his cheek. If they like it, then Shidou don't really mind.

"Then, Shidou. Let's start our training. In order to win those people!"

"Petition. Please take a good care of us. I won't ever forget the taste of that jam."

Said that, they both nodded with determination.

After the battle yesterday, Kaguya and Yuzuru rejected Shidou's offer to share his boxed lunch with them and suck the leftover jam with their fingers to stave off their starvation. They said by tasting the taste of the defeat, they could better sharpen their fangs for the revenge.

Shidou made an empty laugh and looked at them.

"…So in short, you just have to evade their obstacle and get to buy the bread, don't you?"

"That's right. Also, if we could give those 	blasphemer a humiliation they could never forget for their life, that would be great."

"Agreement. What should we do?"

They both nodded. Shidou took out a notebook from his pocket.

The result of the discussion with Reine yesterday was a relatively simple methods.

"Er… first —"

Shidou explained them the method to defeat the Four Heavenly Kings in order in simple words.

"Hmm… I see."

"Understanding. I understand."

Yamai sisters nodded. Shidou closed his notebook and put it inside his pocket.

"Well, like that. If you pay attention to those point, it would be okay."

"Fumu. Then, what should we do?"

"Eh?"

Shidou raised a shrill voice at Kaguya's question.

"Verify. Let's me ask again. What kind of training Yuzuru and Kaguya should take from now?"

"No… to be honest, I don't think that is necessary."

Shidou said while frowning. It was not a lie, nor it was an excuse because he don't want to help them with the training, but it was simply the fact that he thought.

"Well, if you think about it, even though your spirit powers are sealed, your physical ability is far above normal humans. Yesterday was just a surprise attack, there is no way you will lose if you prepared for it. Also, even you said training, nothing will dramatically changed —"

"What are you saying!"

Shidou's words are interrupted by Kaguya's yell.

"We lost to them once! In order to overturn that, there is no choice but to thrown ourselves into the hell of training and reborn as the New Yamai!"

"Agreement. The new skills of the main character are always obtained after a harsh training in the middle stage of the story."

Kaguya and Yuzuru pleaded enthusiastically. Seems like they just want to do the training regardless of the result. …Come to think of it, Kotori said Yamai sisters got hooked to a Shounen Manga back during summer break.

"O-okay, I understand."

Shidou stopped them before they could approached him and thought up of some training program.

"Ah… well, let's do some warm-up exercise with a running."

The moment Shidou said that, the noise run through the wall and the scenery around them turned into a high plateau in an instant.

"O-ohh!?"

Shidou widen his eyes. So this is the function of the virtual training space.

Kaguya and Yuzuru also looked around in surprise and then nodded.

"Kuku… a lightning run, huh. That's fine. First is a warm-up."

"Affirmative. I understand. Kaguya, a race."

"No, even when I said running, I didn't meant for you to race…"

Even though Shidou said that, those two don't take any notice. Seems like even after they could get along with each other, that still don't change how they like to match.

After some small stretch exercise, they both started running.

"Doryaaaaaaaaaaaa!"

"Run. Tou."

They both started with a sprint and circled around Shidou side-by-side with a speed that of a short-distance running.

However, even they are spirits, there is no way they could continued that forever. Not before long, their speed started declining — and Yuzuru collapsed down to the ground with her face down.

"Li… mit…. Uku… u…"

"Ya… haha… I… won —"

Shortly after, Kaguya also collapsed down to the ground.

"H-hey, you two!"

After few moments, Yamai sisters raised up after they caught their breath.

"Kuku… seems like I won this match."

"Regret. As expected from you, Kaguya."

"No, well, I have an advantage over you for this match. It is amazing how Yuzuru could stick this far."

"Question. What is the advantage."

"…Well, you don't have to care."

Even though Shidou noticed Kaguya glanced at Yuzuru's weighty breast for a split moment while saying those words, he decided not to say anything in order to not get involved in a trouble.

"A-anyway, I won! You understand, Yuzuru?"

"Resignation. Ku… there is no choice. The first piece…"

"…The first piece? What are you talking about?"

When Shidou inclined his head, Kaguya come near him with a smile on her face and hold the scruff of his neck to force him to look away from Yuzuru.

"Ouch, what are you doing, Kaguya!"

"Kuku… just keep quiet and wait. You will see something nice."

"Huh…? What are you trying to…"

When Shidou frowned, a sound of clothes rustling is heard from his back.

"Hey, what Yuzuru is doing?"

"Well, we talked a bit earlier. Since we need some tension in our training, we agreed that the one who lose will have to undress a piece of cloth each time."

"Huh… whaaaaat!? W-wait a minute, why are you doing that! Before that, with your current clothes, it is fatal if you undress even one piece of it —"

"Done. It is okay now."

Before Shidou could finished his sentence, Yuzuru's voices could be heard from his back.

Kaguya turned back ahead of Shidou and smiled with "Hohou…".

"Shidou, look at her."

"Wait, I still haven't prepared myself…"

Kaguya turned Shidou's head to Yuzuru like she did earlier.

Yuzuru is standing there with her cheek in red of embarrassment. However, Shidou couldn't tell what changed at a glance.

Not long, Shidou noticed something out of place. In Yuzuru's hand, she is holding a large-size bra within it.

When looking closer, Shidou feel Yuzuru's breast size is larger than few moments ago. The "Yuzuru" label on her breast swayed heavily whenever Yuzuru made any movement.

"Wha…!?"

"Kaka, how was it, Shidou. You can't get enough of it, can you? The beast is rampaging after it has been released from the bindings."

Kaguya said in a pleasant voice while Shidou's face turned red.

"W-why from the inside…"

"Explanation. I have been taught that this is the etiquette."

"It was Reine-san who taught you, wasn't it!?"

Shidou yelled but Yuzuru doesn't seems to mind. Yuzuru held her breast and approaching Shidou.

"Idea. Shidou, I have a request for the next training."

"…Request? What is it?"

"Answer. The training of endurance… in other words, waterfall training."

"Waterfall training… is it that training where you stand under a waterfall? But there's no —"

Before Shidou could finished his words, the noise run through their surroundings and the scenary is changed into a waterfall in the middle of the mountain.

Furthermore, when Shidou tried touching it, he could felt the cold. Seems like the water is real.

"Haha, anything goes, huh…"

While Shidou is making a wry smile, Kaguya stepped forward.

"Kuku… well, I don't really mind. In short, anyone who could stay longer wins, isn't it?"

"Affirmative. That is the case."

After Kaguya and Yuzuru exchanged their glances, they entered the waterfall without any hesitation.

"H-hey wait! You can't do that! Especially Yuzuru!"

"Ukyaa!"

"Amazement. …This is colder than I thought."

However, looks like their match has already begun. They grind their teeth and stood still with their hands joined together in front of them like an ascetic monk.

"Wait…"

Shidou averted his eyes.

It's not strange that he did. Since they entered the waterfall with such light clothes, the gym clothes is now transparent and sticked to their skin.

It might be okay for Kaguya who still have a bra on, but Shidou can't looked at Yuzuru. Shidou's face turned completely red as if a steam is coming out of his head and averted away his eyes.

"Ugu…"

"Endurance.…"

The two keep holding up for a while, but started shivering before long.

"Ahh, I-I-I-I am at my l-l-l-limits…!"

Finally, Kaguya whose lips has turned pale ran out from below the waterfall while holding both of her shoulders.

"A-are you okay!?"

Shidou wrapped Kaguya in bath towel that he prepared during their match. Kaguya keep shivering and squat down on the ground.

"Vic… tory. Y-Y-Y-Y-Yuzuru w-w-w-won this m-m-m-match."

Yuzuru said those words while approaching near. Her shivering teeth is making her unable to speak properly. Like earlier, Shidou then wrapped Yuzuru with a bath towel.

The next moment, the scenery once again changed back into a high plateau. A warm breeze is blown from somewhere.

After their body warm up, both of them raise up their face.

"Kunu… as expected from my other half. Well done."

"Praise. This march was the opposite or previous match. Yuzuru has more subcutaneous fat, so it was my advantage. Applause for Kaguya who could went that far."

"Ugu…"

Kaguya twisted her face in frustration. However, she then let out a breath to change her mood and stood up while fluttering her bath towel.

"…I have no choice. A promise is a promise. Can you turn back?"

"Well, you don't really have to…"

"I can't just run away if Yuzuru did it!"

Kaguya flat-out said so and made Shidou and Yuzuru turned away.

Just like earlier, the sound of clothes rustling is heard… Shidou feel a very naughty scene is being expanded on the back of him and caught his breath without realizing. Yuzuru next to him gave him a look in half-opened eyes with a "Sigh. Pervert." message.

"…It is okay now. I allow you to look at me with those pair of your eyes."

"O-okay…"

Shidou turned back timidly.

As expected, Kaguya who is standing over there don't seems to have any visible changes, except in her hand, just like when Yuzuru did it, there is a —

"Wait, that one is different!?"

Shidou shouted in surprise. The object in Kaguya's hand is not a bra, but for the lower body — in other words, a panty.

"One piece! You don't have anything to complain do you!"

"Assent. Nice thinking, Kaguya."

Yuzuru nodded at her in admiration while folding her arms.

"H-hey, you two…"

"Guidance. Shidou, please look at Kaguya carefully. Even though her appearance didn't changed, however the other side of that piece of cloth is full of dreams. You can't have enough of it, can you?"

"U… gu…"

Yuzuru bend her body near Shidou and whispered him those words. Shidou's cheek turned red at his imagination and the cool touch of Yuzuru's body.

Noticing their behavior, Yuzuru opened her mouth while squirming.

"Let me decide the next match, and let me enjoy that embarrassing looks of Yuzuru!"

"Rejection. It is Yuzuru who will win the next match. I will enjoy the looks of Kaguya shivering in embarrassment."

Said that, both then exchanged their glance. …Even though they could get along well now, Shidou feel they're loving each other a little bit too much.

However, if Shidou leaved them alone, they will definitely cause some trouble. Shidou shook his head.

"S-stop! I will decide the next training! Okay!? I'm your coach!"

When Shidou declared that in loud voice, Kaguya and Yuzuru looked at him with an interested eyes.

"F-from now on is an individual training program! Let's see… for the time being, Kaguya, you do sit-ups! Yuzuru, you do push-ups! 100 times each!"

Shidou instructed them, however they only twisted their face in dissatisfaction.

"What? Different program? There's no way to decide who will win or lose."

"Appeal. And with that limits, there is a change that both of us could accomplished it."

However, in fact, those are exactly Shidou's intention.

If the program is not the same, then there is no way to judge who win or lose. In other words, they can't undress their clothes anymore.

"Don't lose your goal. What is this training was for again? You want to win those Four Heavenly Kings, don't you?"

"Mu…"

"Thinking.…"

They both silence at Shidou's words.

…Even though he is he man who said "training is not necessary" earlier, they both could honestly accepted his advice. Although they seems reluctant, but they nodded to him in the end.

"…It is as you said. Yuzuru is too cute I can't resist not to tease her."

"Regret. Yuzuru as well. I couldn't constrain myself at Kaguya's cuteness."

Kaguya and Yuzuru looked at each other and nodded firmly.

"Well then! Let's do it, Yuzuru!"

"Affirmative. Okay, Kaguya."

They both nodded at each other. Shidou feel reassured at their reaction.

However, for some reason, they both still not lying down on the floor for the exercise, but kept standing in front of him.

"…What's wrong, you two."

"Aa, the load is not enough for a normal sit-ups, so what about I entwine my legs around your stomach, Shidou? I could definitely strengthen my muscles this way."

"Idea. The tension is not enough for a normal push-ups. How about Shidou lying down on your back on the floor and let Yuzuru do push-ups on top of that? The tension of Yuzuru failing will allow Shidou to do anything to Yuzuru's body will effectively —"

"R-Reject!"

Shidou shouted and ordered them an extra number of times for their sit-ups and push-ups.

◇

The next week. September 4th. Lunch break.

In front of the school store, although not as much as last week, are filled with students. Everyone thrown themselves into the battlefield in such a tight space of school store to get the bread they wanted.

However, Shidou and Yamai sisters are not participating in that battle. They are looking at certain space.

— At the showy-looking three persons in front of them.

"Hmp… so you didn't ran away, <Dispel> and the pupils. Let me at least praise that courage of you."

"Kukiki, but that is reckless. Just regret your own incompetent with the bread crust."

"Kyahaha, that is no good, even if it is a bread crust, I am gonna steal it from you~."

The Four Heavenly Kings made a darling smile and confront Yamai sisters.

Kaguya and Yuzuru fixed their eyes at them.

"Kuku, let me return those words back to you. I will make you regret opposing us Yamai!"

"Opposition. As Kaguya said. We won't lose today."

Heard that, <Aerial> Washitani pushed his forehead.

"Good. There are only 20 packs of the limited bread. The stock should be low right now. —Well then, let's start!"

With those words, Yamai sisters and Four Heavenly Kings kicked the floor.

Even still, if they don't do something to the crowd in front of the store, there is no way they could reach their hands on the bread.

"Kaguya! Yuzuru! Plan A!"

When Shidou gave them an instruction from the outer edge of the battlefield, Kaguya and Yuzuru gave him a thumbs-up without facing back.

"Preparation. Kaguya!"

"Right!"

Yuzuru joined her hands, Kaguya then used that as a foothold for her jump.

Seeing that, Washitani who is running in parallel with them twisted the corner of his lip.

"Fu, isn't that exactly the same as before!"

He used the back of nearby student as a foothold and jumped to Kaguya.

"Secret Arts – Icarus Fa —"

"Now! Yuzuru!"

Shidou raised up his voice when Washitani tried to blew Kaguya mid-air with his body.

"Affirmative. I understand."

Suddenly Yuzuru who is kneeling down to the floor started running and jumped into the air —

"Attack. Eiya"

With that unexciting voice, Yuzuru kicked up her right reg — toward Washitani's stomach.

"Oucgh…!?"

Washitani anguished, however, their attack don't stop there.

"Kuku… time for your fall, the former king."

Kaguya twisted her body mid-air and perform an axe kick toward the back of Washitani's heard.

Washitani's body that is receiving both kick up and axe kick at the same time spinning down, and stuck to the floor. His feet cramped a little.

"Ku… Washitani is defeated!?"

"Wha… B-but don't get carried away! Washitani is the weakest of us Four Heavenly Kings!"

Said that, <Pickpocket> Saginuma then made a kinda refreshing face. Seems like she always wanted to say that line.

However, they still cannot let down their guard. There are still two of Four Heavenly Kings left.

"Get this! My death scent!"

<Professor> Karasuma spread out his coat and put several test tubes between his fingers on both hands.

Saw his action, Shidou raise up his voice.

"You two! Plan B!"

'!!'

Kaguya and Yuzuru who have landed on the floor immediately equipped the goggle hanged to their waist after hearing Shidou's words.

When the surrounding began to be scented with the pungent smell, other students started to frown their face. However, Yamai sisters kept calm as if nothing happened. Of course they are, the goggle on their face is the type that covered their nose, like the one used for diving.

"What…!"

Karasuma raised a voice brim of confusion and changed his face into astonishment.

Yamai sisters closes to Karasuma and snatched those test tubes emitting the smell from his hands —

"Kuku, if you like the smell that much…"

"Laughter. We will let you smell it forever."

They then made a devilish smile and pour the liquid in the test tube to his neck.

"Gyaaaaaaaaaaaaaa!?"

After screaming the death agony, Karasuma collapsed down to the floor. The pungent smell in the surrounding gotten even stronger.

"Aw…"

Shidou feel pity at him and frown. Even though he don't know what that liquid is composed of, the smell would probably remained for quite some times.

"Ku… you two! How miserable! If it had come to this then I —"

Saginuma said and tried to sneak up to Yamai sisters.

However, she is then stared by the two, and stopped right away.

Yesterday, when Shidou explained the plans for encounter the Four Heavenly Kings to the two, Saginuma's was the simplest one.

To explain it simply… 'just try to not get robbed.'

Since pickpocketing the bread requires one to be caught off-guard.

Once one pay attention to that, the success rate will drop dramatically.

Now, no one will get in the way of Yamai sisters. They hold the 500 yen coin in their hand and walked to the store, pushing aside the students. But —

"Washitani! Attack <Dispel>!"

Once Saginuma's voice is heard from the back, Washitani who supposed to be crouching down to the floor hold him from his back.

"What…!"

Kaguya and Yuzuru turned back noticing Shidou's voice and distort their face in horror.

When Saginuma saw their face, she made a vicious smile.

"That's right. It is <Dispel> who is giving them the instructions. We should be attacking him instead. — Karasuma!"

Being led by Saginuma's calling, Karasuma who is drifting with a stinking smell rose up.

"Ku… kiki… now it had come to this, I will soak everything in this stinking smell! I wonder if you can stay no reaction when I rubbed you in the face, 'No Reaction' <Dispel>!"

He said that (with a twang) and closes to Shidou like a zombie. Every steps he made cause the stinking smell to assault Shidou.

"U-uwaaaaaa!"

Shidou couldn't resist, and shouted.

"You all…!"

"Anger. How dirty."

Kaguya and Yuzuru distorted their face in anger. However, they already are now surrounded by the students. Even though they wanted to make their ways to Shidou, no doubt Shidou would get hugged by <Processor> before they could be back at him.

"Hey, you should also become as smelly as me!"
"Uwa! E-eek…"

'Shidou!'

The moment Kaguya and Yuzuru simultaneous shouted Shidou's name.

"Eh — ?"

A gust of wind blown all over the surroundings.

After a moment of floating, the view before Shidou's eyes started spinning and his body is slammed to the wall. The next moment, a dull pain runs through his body.

"Aww…"

He opened his eyes.

The view before him is a very strange one.

Centered from Kaguya and Yuzuru who is taking each other's hands, the students are all collapsed down to the floor. The bread are all blown away and few pieces of windows broke.

Seems like some of their spirit powers that has been sealed was flowed back to them at their intensity of emotion. After all, they were originally a spirit of wind who caused a lot of casualties around the world.

"Are you okay, Shidou?"

"Worry. Are you okay?"

They both walked to Shidou then removed their goggles and started smelling Shidou's body. They then reached out their hands to Shidou with a relief.

"Ha… haa… thanks."

Shidou stood up with their help and said with a wry smile.

However, for them right now, they have an even more important thing to do. Once they shook their shoulders, they ran to the school store.
"Store lady, please give us the limited bread!"

"Petition. Please do."

Even though the Four Heavenly Kings are still conscious, seems like they can't stand up right now. They looked at Yamai sisters' orders with a frustrating eyes.

That was the moment of victory. Shidou gripped his fist tight, but —k

"I'm sorry, but the limited bread on the shelf are all blown away just now."
The story lady said with calm voice as usual.

"W… what!?"

"Horror. That can't be…"

Kaguya and Yuzuru looked around their surroundings and slumped their shoulders.

The Four Heavenly Kings who are still collapsing down to the floor then laughed weakly at their looks.

"Fu… fu… how unfortunate."

"Kukiki, so it ended with a tie."

"Kyahaha, then —"

Suddenly — The Four Heavenly Kings stopped laughing.

There is only one possible reason.

From the stairway, there is an approaching footsteps.

"D-don't tell me…"

"This footsteps is —"

"<Miss Perfect> …!?"

"Eh…?"

Heard the voice of those three, Shidou looked at the direction of those footsteps.

<Miss Perfect>. Shidou remembered that name. Those three said she is the strongest of all Four Heavenly Kings.

And she — is now approaching here.

The footsteps come nearer and nearer, and her appearance could be seen.

That face is —

"…Origami?"

Shidou frown and said.

That's right. The person coming down from the stair is Tobiichi Origami.

"<Miss Perfect>!"

"It is been a long time…!"

"I never thought you'd appeared…!"

However, the three of the Four Heavenly Kings looked up to her brimming with emotions. Seems like Shidou did not mistake her for someone else, but Origami is actually the <Miss Perfect> those three said.

"Origami… you are the last of Four Heavenly Kings?"

When Shidou asked that, Origami let out her breath.

"They called me that on their own."

"I see…"

Shidou guessed the situation and smile bitterly.

However, the Four Heavenly Kings don't took notice at Origami's reaction and raising their voices trying to cling to her.

"Please, <Miss Perfect>!"

"Took revenge for us…!"

"If it was you… maybe you can do something even with this situation…!"

"……"

Origami ignored the words of those three and talked to the story lady.

"Pardon me."

"Ah, here it is. The bread you reserved."

Said that, the store lady then hand her a bread (with a 'LIMITED!' clearly written on it) she kept in the back of the shelf.

'What…!?'

Shidou, Yamai sisters and even the Four Heavenly Kings surprised.

"R-reservation…?"

"Amazement. I never thought you can do that…"

Origami walked pass Yamai sisters who is still dumbfounding with the limited bread in her hands.

However, the Four Heavenly Kings are recovered earlier than them and, completely contrast of earlier, made a triumph laughter.

"Fu-fuhahaha! Seems like us Four Heavenly Kings win this contest!"

"Ku-kukiki! That's right! Have you seen the ability of <Miss Perfect>!"

"Kyahaha! Although it didn't sound right to me, it certainly was our winning!"

Origami, not wanting to be involved with them, continued walking without making any reaction. Yamai sisters grind their teeth in disappointment.

"Damn, damn! Even though we put that much effort…!"

"Bitter. Kaguya, please calm down. Let's win them next month."

"……"

Saw their reaction, Shidou scratched his cheek.

For some reason, he feel annoyed if it ended like this.

"…Hey, Origami."

That's why Shidou called her when Origami is going to walk pass him.

"What."

"If it's okay, can we have that bread…?"

"Why."

"Well… a little bit of circumstances. It might not be worth it but, I will exchange my boxed lunch with —"

"Here."

Before Shidou could finish his sentence, Origami handed him the bread.

'…What!?'

The face of Four Heavenly Kings who were enjoying their winning immediately froze.

"Is it okay…?"

"Yes. In exchange."

"S-sure, it is inside my bag. That's now yours."

"……"

Origami heard that and nodded without saying anything then skipped upstairs to the classroom.

"What… I can't believe you could snatch the bread from <Miss Perfect>…"

The Four Heavenly Kings said in a confusing voice.

"As expected from the man who tumbled and evaded my mid-air attack and hit my crotch with your head one year ago…"

"So this means his ability of catching a cold in his nose in order to escape from my death scent was not just for show…!"

"I shouldn't underestimate the man who made me pickpocket the dummy trash instead of the bread…!"

"…Isn't that all a coincidence?"

And so that's why he has been given the nickname. Shidou dropped his shoulders listlessly.

Few seconds later, Yuzuru and Kaguya who finally understood what's going on ran to Shidou.

"Shidou! You did it!"

"Praise. You did it at the end."

"Well, it's kinda dirty play though."

However, for Yamai sisters, the fact that her comrade able to get his hand at the bread is important. Kaguya hugged Shidou with a broad smile and Yuzuru happily lean herself toward him.

Shidou made a bitter smile and hand the Rainbow Cream Bread to them two.

"Good job. — Here, divide it between you two."

'……'

However, Yamai sisters who received the bread from him stared quietly and it, and took the bread from its package then divide it into three pieces.

They then gave the middle piece to Shidou.

"Eh?"

"Kuku… I'm indebted for your work this time. Let me give you a reward."

"Gratitude. Our winning is because of Shidou. Please accept it."

Shidou surprised for a little while… then raise up the corner of his lip and accepted the bread.

"I see. As you wish, then."

"Umu. What about doing a toast at our winning?"

"Consent. Let me borrow your hand."

"Toast?"

While Shidou is still inclining his head, at the bread in Shidou's hand, Kaguya and Yuzuru touched their bread to it.

Seeing Kaguya and Yuzuru's satisfying looks, Shidou bit into the bread.
