Kirishima's sister.

Pt.1

Y/n's quirk: Switch.

In which she has a second personality. Basically her opposite. This thing is a voice in her head but can take control of her body. It is influenced by strong emotions however negative ones make it even stronger.

The second personality has advanced physical and mental abilities and can read and take control of people's minds. However taking full control is a bit of a struggle.

She calls this thing Nanika.

A bit about y/n's appearance: The image above is kinda how i imagined it. Like Kirishima you have sharp teeth but it's just you canines.

This won't start off fallowing the exact story line but it will soon and chapters will be longer.

_________

You walked into class and took your seat by your brother.

It was the first day of class. You never expected to actually get into UA much less class 1A. You were beyond excited. So exited you hadn't slept more than an hour last night.

However despite being tired you kept your smile on your face as you talked and laughed with your brother.

That is until the teacher comes in... Or inches in while curled up in a sleeping bag.

He introduces himself as Aizawa, your teacher and says you'll be doing placement tests.

You all changed into gym clothes and you went to the training grounds. There, you met up with your brother.

As he started explaining it didn't take long for you to figure out he was lying about expelling people.

You went through all the placement tests. You passed pretty easily by using Nanika's advanced abilities. If you used them without letting her take over they wouldn't be quite as strong but still advanced. And thats what you did.

The last test came and you were doing a ball toss. Bakugo was called to go first and he did really good. He got 705.2. When it was eventually your turn you walked up and used the advanced abilities again, however you didn't let her take control.

You were just about to throw the ball when you realized you couldn't use your quirk. You turned to see Aizawa erasing it.

"You wanna be lazy and not use everything you've got then you can leave now. I saw what you did in the entrance exams. You've been using half your power this whole time. I've let it slide so far but not anymore. Show me everything you've got." He says sternly.

You stare at him and glance at the ball with a slightly worried expression. The only thing about when Nanika takes over is that you have NO control until she gives it back.

You sigh and nod in agreement. Holding the ball firmly in your hand before turning back to Aizawa. "As soon as I've thrown the ball, erase my quirk please." You say. He looks confused but nods.

You close your eyes and let Nanika take control. You let your own thaughts and consciousness slip away as if you were laying down in a perfectly calm pool of water.

When you got control back you looked around to see the ball nowhere in sight, Aizawa had erased your quirk, giving you control back. He checked the thing and showed you. "800.7, Good job." He says calmly.

"Thank you sir." You say quietly but politely and walk over to your brother. "What happened?" You whisper. You never remember the events that take place when Nanika takes control.

"Don't worry. When you opened your eyes she just asked if she should hold back and Aizawa said no. She threw it and it went super far. Then he erased your quirk." Kirishima explains.
