St.Orca's Secret Operation - Stage 1

Opening

The bridge was quiet. When I took my eyes off the computer and stretched, my body screamed.
Maybe I should take a break...
Time goes even in a world in ruins.
Does the iron-bugs even have the concept of the end of the year?
They have not made a big move these days.
Thats great for us, but as a commander who leads many bioloids, there is a lot work to be done.
There are many documents waiting for my approval and they are unlikely to stop coming.
Even when some bioloids help sometimes there is still too much...
Someone approached me as I tried to get rid of my stiff shoulders and neck to get back to work.

Constantia: Master you look very tired, why dont you take a break?
            It will be worse if you get sick.

...Do I look really tired?

Constantia: I know it because I have been taking care of Master for a long time.

She looked at the computer and started to type.
I sigh seeing the letters filling the screen.

Constantia: Please do not carry such amount of work all by yourself...

Sorry

Constantia: If you really want to apologise, please go to your room and rest.
            Ill do the rest of the work for you...

I tried to refuse but I reflexively say "Okay",
I swallowed my words when I saw Constantia worried face.

...Alright. Ill take a little rest.

Constantia: Yes Master.
            Please rest well.

I headed to the captains room while biting yawns many times.
When I was conscious that I really needed a rest, I suddenly missed my bed.

Doctor: Thank you for your hard work~

Eh... Thank you too Doctor~
I continue walking down the aisle, greeting the girls as usual.
For the time being, take a break in my room then the next job would be...
Oh, I have to check if there was anything wrong with the scout group Khan was leading...
And also since its Christmas I need to prepare some present for the members that are always doing their best...
Eh...?
What was that earlier?

Doctor: Thank you for your hard work~

I was exchanging greetings with the girls then a Doctor-like bioloid passed me.
I dont think the voice is too different, but... the braids are clearly in different positions...
Doctor...?

Doctor: Yeah? Whats wrong~? Onii-chan?

...
The bioloid who looked and smiled me back was still "Doctor"...
She looks like she has grown up 10 years suddenly... Is my fatigue making me see things?

Doctor: Whats wrong~?
        Pupu...
        Puhahahaha! I cant stand anymore! Yes! Finally done~!
        Im an adult Doctor~!
        Onii-chan! Onii-chan!
        What do you think?! Amazing right?
        Doctor was really excited.

Because of that, her clothes werent able to contain completely that body...
Oh! Thats the research you were always talking about!

Doctor: Eh~? Why are you looking away onii-chan? I had a hard time~!
        Do I look like an adult now?

Yes! Doctor! You do!

Doctor: Guhehe, then dont hesitate...

Well, Keep up the good work! With this Im...

Doctor: Eh?! Onii-chan?!

This is bad! I need to run! If had continue talking with her things would have been definitely bad!
I know it was mean to Doctor, but I forcibly cut the conversation and started to run.
I desperately tried to ignore the sound of the ominous slippers chasing me from behind while I was escaping to my room.
When I opened the door, the familiar room was gone, instead there was this totally unfamiliar fluffy room...
What is this?!
I was completely paralysed by these continuous shocking events that Doctor finally caught me.

Doctor: Surprise~! Ehe~! For onii-chan who is always working hard for us!
        The design was done by me and Fortune onee-chan, Constantia and the other onee-chans helped too.
        Ihihi~! What do you think?! Your are impressed, right~?

When I stroked my head, Doctor eyes became round.
Yeah, Im really happy. Thank you.
The room had a Christmas atmosphere.
When I saw every corner carefully decorated I mysteriously saw everyones feelings for me.
Impressive, Im very happy.

Doctor: Fufufu, ehehe...
        Onii-chan, Onii-chan. Dont just stand in such a place, sit here.
        This sofa is very fluffy, isnt it?

Doctor pulls my hand and makes me sit on the sofa.
She naturally sits on my lap.
I feel Im loosing my reason since her scent is totally different from the previous Doctor.

Doctor: Ihihi, I like this...

The back of her adult body approached me...
Feeling the danger, I hurriedly bend my upper body.
Because of that, my body sank deep into the sofa.
Well... Is that research done?
I observe Doctors body, carefully not to dig my own grave.
She easily grew her body.
Although it is a tremendous invention, it doesnt seem to be a big deal for her...

Doctor: Its not done completely, Its still a bit unstable.
        Mass production is difficult at the moment...
        I used it in myself because I was in a hurry this time,
        but in reality I have to do more clinical trials...

The Doctor I always new started to explain it before I realised.
Alright, as planned.

Doctor: In fact, we already have the technology to grow or replace our skeleton.
        However, the process is complicated, cumbersome, costly and time consuming.
        I tried to simplify it to some extent.
        Its weird, if you take a bottle of medicine... Puff! You get transformed!
        Im going to prepare different flavours. I made it strawberry flavor this time.
        It was better than expected.

A girl who enthusiastically explains with shining eyes.
Before, she was just cute, now she is giving an aura of an intelligent and beautiful adult woman...

Doctor: Even though the first clinical trial was successful,
        getting a complete finished product its going to be a long way.
        When this research is completed... Oh, I cant say it now.
        I have to surprise onii-chan again~

I reached my hand to pick up the cheeks of the laughing Doctor as usual, But I realised...
Can changing her appearance make me conscious about her...?
Can you give me a hint of what are going to do when its completed?

Doctor: Ihihi~ What should I do~?
        Hmm...
        This is for onii-chan and for us.
        Thats it! The hint is over!
        By the way~ Ill be waiting for you...

Doctor who turns to look at me laughs meaningfully.
Seeing her body... I feel the danger...
No! The front is too dangerous!
I managed to keep distracting myself,
but the area of contact between me and Doctor gradually increases...
Desperately enduring this body, my reason was going to evaporate.
I thought about changing topics...
Then a good idea came up!
Doctor! I need help!

Doctor: Yeah? What kind of help~? Ihihi...

Santa!

Doctor who was going down suddenly stopped and made my eyes flutter.

Doctor: ...Onii-chan are you okay? Do you need to sleep?

.....

Not even a chuckle, she seems to be seriously worried.

Doctor: Do you really want to see santa?
        Onii-chan is still a kid because he still believes in Santa!

Thats not what I meant...

She might be crazy, but she is a scientist to the root.
Shes realistic in strange places...

Doctor: Why dont leave the fairy tales for the kids? We are adults...

Doctor put his arms around my neck, but fortunately someone came in.

Khan: Commander, the situation about the reconnaissance mission...
      ...Are you enjoying it?
Doctor: Ah? Khan onee-chan! Hello~

Doctors cheerfully greeted her while proudly sitting on my lap.
Khan just stood silently.
Doctor, move a little... What happened?

Khan: Hmm? Is it really okay...?
      During reconnaissance, I sensed the crash of an U.F.O.
      You could see the rising smoke from the crash point with a naked eye.

Is it an iron-bug?

Khan: No, no iron-bug signal was detected from the object.
      However, the iron-bugs scattered around are approaching the crash point all at once.
      Reconnaissance team is enough to deal that amount of iron-bugs. Orders...
Camel: Mo~ Captain! You have talked to the commander for the first time in a while,
       but its such a stiff way of speaking.
       Its not good~
       Yahoo, commander~!

Yoo. Wasnt Werewolf with you?

Camel: That idiot was being noisy and for some reason fell into a hole.
       Now Im drying my clothes and equipment from the snow too.
       Shes here, would you like me to call her? Werewolf! Come here!
       Oi! Get dressed! Im talking with the commander!
Khan:...

Khan, who was looking at her subordinates, had a smile on her face.
It looks like you are in good terms.

Khan: Well... Yes... Oh, we are derailing from the topic.
      The scouts in this area have determined that they can defeat the iron-bugs on their own.
      Its better to go to the crash point to check the flying object.

Alright, please contact me if you have any news.

Khan: We will immediately wipe out the iron-bugs and head to the crash site.

Oh, wait a minute.
Unlike Khan who went through the fall, Camel and Werewolf arent used to the snow like her.
Im worried about Camel and Werewolf because is a snowfield operation.

Khan: Please continue.

Can I take the command?

Khan: Hmm...

Is not that I dont trust you, Khan. Im sorry if you are offended.

Khan: You dont have to apologise. There must be a reason for you to propose that.
      Alright, we are in your hands commander. Lets start the operation.

Ending

Khan: Your orders were wonderful as always commander.

Thank you, but everyone fought well.

Khan: Our scout team heads to the crash point at the moment.
      Thats it.

Doctor, who was sitting next to me on the sofa and hanging her legs while waiting,
sat on my lap again giving me her back as soon as the report was over.
Will this continue...

Doctor: Hey Onii-chan, why did you suddenly say that you wanted to be santa?

Oh... you see...
Ever since I woke up in that abandoned building...
I couldnt remember anything other than combat knowledge.
Im sure I would be useless if it wasnt for the girls in the Orca.
No, Im sure I wouldnt have survived to this day if it wasnt for them.
I want to give you girls back the favours as much as possible.
I tried to put feelings hidden in my heart with words one by one.
How happy and grateful I was.
Everytime I said it, Doctors eyes shined brightly.

Doctor: Onii-chan...

So I wanted to make a surprise party and give you all presents.

Doctor: I see... Thats what you meant! Now I understand.
        Hihihi, Im looking forward to it~

But its really difficult to do it alone... Doctor can you help me?

Doctor: Of course! I know it would be difficult if you do it all alone~!

With that said, she stretched her spine while raising her index finger.
If possible, please stop this suffering...

Doctor: Of course we need to make gifts, and we are doing a party, food and decoration.
        Besides, I have to secretly prepare something...
        Oh, is that okay?
        When it comes to carrying things... The backpacks used by Sylky onee-chan...
        Will they have any of them to spare?

She got lost in her world before I knew it...
Is this the end of this crisis for now...?
Ive often seen other girls summarising their thoughts while talking to themselves.
Looking at it as an adult in this way, Im deeply moved.
So much things... Big... Various things being big...
Big...
Doctor, is it okay?

Doctor: Speaking of it, the city in front of me... Ah? What?

Lets do something with those clothes first.
There are many girls in the Orca that walk around with clothes that transcend my imagination.
I thought I was used to such visual stimuli, but I was wrong.
...No that I was proud of it.
She is overflowing in a different sense from the usual Doctor,
this aura of an intelligent and beautiful adult woman...
These two appeals are overwhelming.
They are not good for my sanity.

Doctor: But I have not found clothes that fit my size yet.
        Audrey was also busy...
        Whats wrong with this? I like this new feeling of freedom a lot~

That Doctor part that I barely see is now flipped over.
...Oh my Orca...

Doctor: Oh! Yes! I almost forgot!
        Onii-chan, you said that you would "Love" me when I grew up?!

Ahh, About th-...?
She didnt wait for me to end what I was saying and turns around and faces me.
I was able to resist previously since I only saw her back all this time,
but my reason got a critical hit when she moved again.
Those lips this new Doctor has.
Her new face has a new level of power.

Doctor, It doesnt matter if you have the body of an adult...

Doctor: Then what do I need?

You have to grow up in my heart...
I gently stroke Doctors head.
Could you help me to become Santa for now?

Doctor: Um...

You are the only I can count.

Doctor: Ummmmmmm...

I need you Doctor...

Doctor: Uh... If you ask me so much... I guess it cant be helped...
        But when this is over, you will definitely "Love" me, right?

Ill do my best.

Doctor: Ihihi, Is a promise?

Doctor took my hand and entwined my little finger with hers.

Doctor: But is it really good, Onii-chan?

What?

Doctor: Onii-chan has a lot of work to do, also you will have to make presents and prepare the party.
        You will have to move a lot, right?

Ill deal with it, dont worry about it!
I stroked Doctors head again.

Doctor: I hope Onii-chan will be okay...
        Lets start now! There are a lot of things to do!
        Hurry! Lets go!

After seeing Doctor leave the room and disappear into the aisle, I sighed with relief.
That was dangerous!!!
No matter how mature she looks, she is still a child inside! Hahaha...

Doctor: Onii-chan! Hurry!

Ahh?! Yes! Lets go!
I tried to get up, but my legs didnt have energy so I sat down again.
Dangerous, really dangerous...
