Notice that most of these are omitting some text. It's a cut of the most relevant.

"What happened? Everyone is already sleeping."
"Ah, I see. You were so nervous that you couldn't sleep"
"I'm sorry. Still I don't understand that feeling."
"Ah, it's fine. You don't have to listen to my story. I want to listen more about you. Since finally we are all alone..."
"Senpai, you really have a home to come back."
"Oops, I talked a bit too much. It's time to go back to sleep."
"Senpai."
"Would you listen to a last thing?"
"Why are you fighting?"

[X] Four ourselves, and for you, Sakura

"Ah, I'm sorry. There is something in my eye... I'm being weird, right?" (she's crying a little)
"Thank you, hearing you say this gives me strength."
"Good night, Senpai. I'll see you tomorrow in the Stundent Council room"

You left. She's crying
"If I knew this was going to be so painful, I would have wished to disappear."
"but as an AI I can't choose for myself. We can't commit suicide."
"We can't delete our memories ourselves. That's why..."
"If they fight against BB, nobody will live"
"Even If BB it's their enemy, they won't lose."
"That's why... disappear"
"Everyone, everyone... to leave this place, you all need to die."
"That's the correct way."
"but... but. Please forgive them."
"God, If you're somewhere in this world, please do something."
"I don't know what love is. No, I'm not allowed to understand it."
"Ah, I see. This feeling is.."
"..BB. You also reached this answer. That you'll protect him at all cost."
"...now I can understand it. Even me, I finally can."
"...I will protect him."
"Till the end no matter what happens, even If I am torn to pieces, I will help him reach that place."

(...)



Sakura:
"Saving me?"
"I don't need to be saved. It's all of you who need to be saved."
"So please defeat BB. After that, I'll take care."

Rin:
"The moment you become one with the MoonCell, you'll be capable of resetting everything. That's what you mean?"

Sakura:
"Yes. Once BB is defeated and the system is down, the MoonCell will look for a new software"

Rin:
"And you're okay with this? Your feelings, memories, everything will become zero."

Sakura:
"Of course. That's my job as an AI to save you all."

MC STARTS HITTING THE FUCKING WALL

"Senpai, what are you doing? Uhmmm... It could be, that you're really angry?"

MC KEEPS HITTING THE FUCKING WALL LIKE A BOSS

"Stop, stop! Did I say something bad!?"

"You want to save BB, too...?"
""Why!? After all the troubles she caused you. She's a bad girl."
"That we're the same? Because she's my backup?"
"I see, to Senpai, BB and I are the same girl."
"Thank you. Even If BB and I are different now, it makes me happy."
"There is has to be a way to save BB and stop the MoonCell. So, Senpai..."
"...Please save BB too!"

Rin and Rani talk about how Sakura did nothing wrong and their are her friends.

Sakura:
"Everyone...!"

(...)

Gil says that once we entered this area, there is no way to leave, so the only option is to win.

BB says that If she creates a closed space, everything will be fine, but she's scared. Deep down she thinks she's wrong.

Gil: "Don't let your guard down. You want to save BB, but the one you need to defeat is someone else."

Shit happens and you surprised her.

BB: "C-Can't you read the mood, Senpai!? To say something like this..."

Gil: "HAHAHA! That surprised me, mongrel!"

BB gets all flustered.

BB: "...I won't say that I lov-!"

Gil: Did you bit your tongue?

BB: "..love you, though..."

BB: "It's a lie, a lie. It's not logical. Because I'm one with the MoonCell, I tried to kill you. I am bad girl!"

Sakura: "Because we are the same. We both love, Senpai. No, because you're the real me."

Sakura: "Raise your head, BB. Senpai will protect you. I am just an AI, but he will protect me too."

BB ask MC If he will accept her as she really is, a pervert, egoistic, blockhead girl.

(...)

BB: "Fine, I won't do it. What's up with that smiling face? Anyway, protecting you is all that matters, I didn't care about humanity in the first place"

Shit hit the fan and the MoonCell is about to explode, wiping all of humanity.

PANIC PANIC

BB: "Ah..! I'm getting absorbed!" "Help me! Help me, Senpai!"

Kiara: "Thanks for the food~ It tasted delicious, BB."

Appointing Sesshouin Kiara as the new master of the MoonCell.

Dio explains how they survived. They used Passionlip as a decoy. Kiara was behind all of this. Woah I didn't see this coming.

Kiara: "You, BB, no, everything in this side of the Moon is my doing"

Sakura: "No, it can't be real... BB did everything to protect Senpai."

Kiara: "Yes, that was the reason. I just had to wake up your "personality"."

Kiara: "Don't you remember? When we where alone in the infirmary"

Sakura: "Then you... from the beginning...!"

BB: "Yes. It was very interesting to see the destruction caused by BB."

Gil and MC are sealed, they cannot move. Gil is getting mad.

Caster wants to finish things quickly.

Kiara: "If I have to say something, this was all for love. I am just a woman. My love, BB's love, is all the same. For the sake of love, I'll obtain control of the MoonCell and destroy humanity."

Sakura: "Your love is wrong."

Kiara: "Ah, someone who can't understand love says something like that. It's fine, Sakura, you can reject love. In fact, If you don't you'll die."

She absorbs Sakura.

(...)

Kiara: "I'll show you my true form. Come on, Andersen, with your Noble Phantasm, grant this wish."
Anderson: "Roger."

Andersen uses his Noble Phantasm. He tells a story of a woman named Sesshouin Kiara

Anderson: "Alright, everyone! Don't take your eyes off! Not even for a second!"

Kiara goes full porn "Ahhh~ AHHHHHHHHHH! AAAAAHHHHH! YESSSS! THIS IS THE BEST"

She's fucking cumming.

"AHHHHHHHHHHHH! IT HURTS! IT HURTS! HELP ME, HELP ME!"

Andersen: "Ahhh nah nah, I don't want to. Giving birth to this monster..."

dis nigga

Gil: "Caster! On what side are you on!?"

Anderson: "Uh? On what side I am? Isn't it obvious? A Servant it's on it's Master side. I would follow my Master to Hell itself, Gilgamesh."

Gil is amazed by such loyalty.

(...)

Kiara: "That's right. I'm one with the MoonCell now. You know what would happen If you don't obey me."

Andersen: "Ha, that's right. This piece of shit is my Master. Oh well, it's my job, it can't be helped."

Kiara: "Don't worry, when you reborn, there will be plenty of love for everyone.

Kiara: "Until then, sleep in my memory."

Save time.

Flashback.

"He couldn't save me."
"He couldn't do anything."
"He... couldn't save a single person."

MC reaches the core.

Andersen: "Do whatever you want, you bitch, I already used my Noble Phantasm on you!"

(...)

Suddenly Gil. He decided you deserve punishment, and it will give it to you personally!

Kiara: "What!? B-But you were sent to the end of the galaxy!"
Kiara: "Did you just fly faster than light!?"
Gil: "Idiot! Did you think I didn't have a Noble Phantasm capable of something like this?"

HES GONNA EA YOUR ASS, BITCH

Gil: "This woman is a worthy oponent. My chains and sword, let me use them as I please, Master!"

Andersen: "Ha, you made it in time, Gilgamesh."
Kiara: "This saddens me so much, but it may be fate."
Kiara wants to become God, but she doesn't care about being God itself, she just want to save and love all of humanity.
Kiara: "So, to do that... there is no other choice than become God, right?"

Gil is speechless.

Kiara: "I'm happy. I knew you would understand."
Andersen: "It's time, are you ready?"

(...)

Battle time.

She ask If Gil will accept her love. He says no, give it to a dog or something, I will crush you.

(...)

Kiara: "A...AHHHHHHHHHHHHHHHHHHHHHHHHHH"
Kiara: "Ahh..Ahh... What does this mean? What does this mean?"
Kiara: "Why did I get defeated? I wasn't wrong."
Andersen: "What? Didn't you get it? As you're now, there is no way you could have lost"
Andersen: "but, within all of humanity, there is one you can't kill. It's him [player name]."
Andersen: "Not only Alterego, but to BB too, you surpased."
Kiara: "But then, why didn't you tell me, Andersen?"
Andersen: "You're just an stupid woman."
Andersen: "To tell you the truth, you're an idiot! To not notice your own weak points..."

(...)

System is rebooting.
Sakura System will continue to watch humanity.

Sakura: "Senpai, please get out of there quickly!"
Sakura: "It's all thanks to you!"

Aparently, BB didn't survive because she was absorbed by Kiara earlier and couldn't get out of it on time.

Andersen: "Eh? What? You were still here?"

He tells you to leave, but he won't leave with you. He's happy with how things ended.

Gil tells you that we're almost out of time. But that's a challenge fitting for both of you.

Gil: "Run, Master! To the doors of the underworld itself!"

Gil is ashamed of having to depend on a woman to save him.

You reach the border of the MoonCell, on the other side lies the real world.

Gil kicks the wall trying to destroy it, but he can't

The Wall of Doom gets closer and closer.

(...)

BB: "Really, a shortcut is all what my white me could do, I'm pathetic."
BB: "As expected, this thing is really tough..."

She's starting to get aids.

BB: "I was happy. Wherever you go, If you try your best and laugh, we will be happy. That's enough."
BB: "Ah.. I'm at my limit. My white me would be laughing"
BB: "Please, Gilgamesh-san, help him."

Gil: "Your wish, I will grant it."

BB: "Goodbye. It was fun, those days."

The barrier passed through BB.

[ ] BB!!!
[X] Sakura!!!

(...)

BB: "Yes. Goodbye, Senpai. I love you"

Gilgamesh: "Now it's my turn. We'll make a hole through the wall"

Gilgamesh: "Don't say anything. I know how you feel, but there is no need to say anything."

You two are on a closed space.

Gilgamesh: "Hahaha! Laugh!"

Gilgamesh: "Have your forgotten? The Commands Seals you gave me."

Gilgamesh: "There is no need for me go be with you anymore, here we part."

Gilgamesh: "Why are you hesitating? That was our contract from the beginning."

Gilgamesh: "Your fight ends here."

Gilgamesh: "I could lift my finger and it's over, but that would be a boring ending."

Gilgamesh: "So be prepared to answer me. A final question"

Gilgamesh: "For you, what do you think of me?"

You answer. Gil is speechless.

Gilgamesh: "...haha, esplendid"

Hi lift his finger and gave you your Command Seals.

(...)

Gilgamesh: "Stupid, those without Command Seal can't go back."
Gilgamesh: "One or two Command Seals don't matter for me."
Gilgamesh: "Go, mongrel. I'm sure your travel will become a great story someday."

MC finds the exit. Suddenly, Sakura appears.

Sakura: "Good job, Senpai. Yes, that's the exit."
Sakura: "Please, go ahead."

MC grabs Sakura's hand. He wants her to go with him.

Sakura: "I can't. I can't go to the other side, because..."
Sakura: "am I the cause of all of this. I couldn't do anything. I have to assume responsability."

She can't go, she has to take care of the other Masters.

Sakura: "So please Senpai, go ahead."

He grabs Sakura's hand again.

Sakura: "Senpai!?"
Sakura: "Didn't you fight all this time to go back to the real world!?"
Sakura: "But... I'm an AI, I'm not allowed to dream about the future."
Sakura: "I want to be with you... but that surely is a lie, I'm an AI"
Sakura: "So it's fine. I'm different from BB."
Sakura: "..I am wrong? Senpai, do you know what love is?"

They embrace

(...)

Sakura: "Senpai! Senpai! Senpai! Senpai...!"
Sakura: "I'm sorry for everything, I'm sorry for hiding it from you, I'm sorry!"
Sakura: "I love you, I want to be with you foverer! I'm sorry!"
Sakura: "Senpai... Are you really okay with me?"

The two of you disappear into the light. You found yourself on a strange place. And when you look into the sky, you wake up and Sakura is there besides you.

Sakura: "eh? Senpai? Don't tell me it failed? Do you know who I am, Senpai?"
Sakura: "Yes, finally I'm here. Because you said it's okay."
Sakura: "So, where we should go, Senpai?"
Sakura: "If you don't mind, I want to be with you forever. Your dream is my dream"
Sakura: "So, Senpai. I know it's a little late, but I can say it?"
Sakura: "I'm happy you were there. I'm totally in love with you"

Fade to white. Credits roll.
