Did I ever tell you that I have a BNHA OC?

Because I have one

And she's (very cliché, I know) family from someone of BNHA

Try and guess

Though it isn't hard at all

Name: Kirishima Kaida
The other possible name was Kirishima Ryoko. And if she wasn't family of Kiri, her surname would've been Himura.

Hero name: Glitch

Quirk: Teleportation
Basically she can teleport to any place in sight. However, if she's stuck, or can't move freely, she can't use her quirk anymore. She can teleport other people too, by grabbing them (it doesn't matter if they're stuck somewhere).
When her emotions get get stronger, she will sometimes teleportate quickly in very short distances (therefore the name Glitch).

Class: 1-B.

Personality: Is a lot like Kirishima's. Don't really know exactly how to describe it right now. I will do it eventually.

Hair colour: Black.

Eye colour: Red.

I have two options of how she's related to Kirishima:

Twin sis. If that would be the case, it would be weird if they have different quirks. It is possible of course, but it's rare.

Cousin. She and Kiri have always been very close, their dads are brothers.

How she passed the entrance exam: She already expected the exam to be a fight, so she wore heels.
She teleportated (is that correct?) on top of the robots and tried to kick them as hard as possible with her heels. It took a lot of time, but she did manage to get quite some points, and thus ending up in class B.
