Hi, this is my first fanfiction so I hope you enjoy it. If there is anything you think I could be doing better, CONSTRUCTIVE criticism is appreciated. Telling me that this fic sucks without giving me a way to fix it will not result in a better fic, just an incredibly pissed off author.

PROLOGUE:

-(Warehouse)-

'I need to get out of here' was the only thought running through a 10 year old Ichika Orimura's mind as he was currently tied to a pole in a warehouse.

If anyone were to ask what circumstances lead to him being here, they would have to give you the history of IS and the Mondo Grosso, a competition between IS pilots, because this is what led him to be here.

Looking around, Ichika notices several things. An IS 'Not very helpful as only females con pilot one', and a shard of glass which came from a broken window which was sitting near his hands. (A/N. I know, this is convenience and stupidity at its finest. Sadly, it's necessary for the plot to last past the prologue.)

'The person who tied me here is a moron, he left me a way straight out of here'. In said morons defence, he probably wasn't expecting a 10 year old to be thinking rationally in this situation.

Ichika grabbed the glass and used it to hack at his bindings. This being a tedious process led to Ichika to creating a plan to follow after he freed himself.

'1. Get unbound. 2. Find out where guards are. 3. Evade guards and escape warehouse. 4. Contact authorities and Chifuyu-nee so they can sort this mess out.'

Several minutes passed as Ichika cut at his bindings. Once he was free of the bindings, he promptly abandoned his plan by walking over and standing by the IS, an Uchigane, if he wasn't mistaken.

Which he rarely was, as an insanely intelligent boy. Tabane Shinonono level insane. Seriously, he tested out of high school only this last school year. This means he also has several eccentricities, one of which is to abandon a train of thought on a whim which was just demonstrated (Also an obsession with making a pair of ears like Tabane's).

This also means that by looking at the IS, he sees several things he would do in order to improve a personal IS in general. "Shorter legs and arms which are long enough to allow height and reach but no more than 2 feet longer in the arms and 3 in the legs." Ichika began to mutter under his breath. "Thinner legs and arms, only two to three inches wider on the inside than the widest part of the pilot's limb. Programming to accommodate the growth in the pilot's body by to make IS comfortable. Minimize size of wings in order to decrease mass similar to leg and arm modifications would increase thrust capabilities without increasing thrust output."

'Maybe I need to talk to Tabane-nee after all of this is over' Ichika thought to himself.

Meanwhile, outside the warehouse he was in, gunfire started sounding off. 'What the hell.'

One of the men who kidnapped Ichika came back into the room and noticed Ichika was no longer bound in his spot by the pole and looked around. Upon seeing Ichika by the IS he shouted "Hey boy! That thing won't work for you anyway so why are you near it" and ran up to Ichika grabbing him and pinning him against the IS.

A small glow appeared around Ichika's hand where it came into contact with the IS. "Impossible" was the only remark from the man pinning Ichika.

Inside Ichika's head a voice not his own asked. Do you wish for power?;. 'Yes'. ;I can put you on the path to power, but the journey's beginning will be painful and I will not be there to accompany you to its conclusion;. 'I do not care about the pain as with the power you can give, I can become stronger to protect myself and all those I care about'. ;You have potential that many others can only dream of, and for that alone I would have started you on this path. With your noble cause, I am unrepentant in giving you this power as I can see you will use it wisely;.

The light on Ichika's hand expanded around Ichika to the point where he was fully engulfed by the light. At this point, three things happened.

The man pinning Ichika backed up rather quickly to the other side of the room.

Chifuyu entered the room in her IS [Kurazakura].

Ichika started screaming as his DNA was being rewritten to allow him power.

"Ichika!" Chifuyu Orimura, Ichika's older sister shouted while disposing of the man who was cowering away from Ichika before she went to him and tried to figure out what was wrong. That was when she noticed the IS next to him and had a reaction very similar to the other man. At this point she was panicking heavily when the light begins to die down along with Ichika's screams.

When the light has almost fully dispersed, Ichika begins to drop from being unconscious from the pain he went through and Chifuyu immediately reaches out and catches him.

Looking at her brother Chifuyu is shocked by what she sees. Her little brother doesn't qualify for that title anymore. Ichika has changed, to put it lightly. Immediately noticeable is the long, dark hair, not unlike her own, and the softer, feminine features of the face whereas before the hair was short and carried a heavy blue tint which was now gone and sharper, more masculine features which would be found on a boy.

Chifuyu is certain that this change is not only a complete transformation (ALL of Ichika's body is now female), but that it is also irreversible. She also knows that the one person able to help her understand what happened fully is currently unconscious in her arms.

-(Hospital, 1 Week later)-

Chifuyu is currently next to a hospital bed whose occupant was once her little brother although now is her little sister.

As she expected, the transformation is a complete one. That is, Ichika is now a girl and it is permanent.

Ichika has yet to wake from her coma which happened after the transformation was complete. This is why Chifuyu is here. To offer support to her sister when she wakes up if it is necessary.

(A/N. For conveniences sake… again) A soft groan from Ichika alerted Chifuyu to the fact her sister was waking up now. Ichika's eyes slowly open and once they have refocused they find themselves locked on Chifuyu. "Chifuyu-nee" Ichika whispered as her voice was weak from not being used for several days.

"Hello Ichika" Chifuyu said softly. This set off alarm bells in Ichika's head 'What's wrong that it would make Chifuyu speak in that kind voice, it must be very bad'.

"Chifuyu-nee what's wrong?" Ichika asked with some more strength behind her words. This was when she realised that her voice was different and a frown crossed her face in trying to figure out what caused it.

"Ichika, by the look on your face I think you have noticed there is something is different about you now, so I will tell you what we know of what happened". Chifuyu began. "When you came into contact with the IS in the warehouse where you were kept after being kidnapped, something strange happened. The IS interacted with you for some reason and when it was finished, your DNA had been rewritten. Ichika, the IS made you a girl". Chifuyu ended bluntly in order to minimise the damage when Ichika reacted as her sibling had a tendency to explode violently when someone takes too long to explain something.

"EHHH! It changed me into a girl!" Ichika screamed in the high pitched voice that now belonged to her. Taking a few calming breaths, Ichika began to think out loud. "So this is what that IS meant when it said it would put me on the path to power, it was also right when it said that the beginning would be painful. I know I have the potential to do well as the IS said, now I need to put this potential into motion. I am however starting to wonder why I agreed to this in the first place".

"O.K. I understand Chifuyu, I don't like it but I understand". Ichika said in a progressively weaker voice as she started to fall asleep again.

'Sleep well Ichika, because what I didn't tell you was that every media outlet around the world already knows what has happened here so you are in for a hell of a time in the near future. Hmm, I wonder if I should call in some of those favours Tabane owes me to keep Ichika safe with her until she can go to IS academy in 5 years'

Well that's the prologue done. Hope you enjoyed it and hopefully I will get up the next chapter in a few days at the most (Maybe a week).
