Izuku's lil sis

Izuku has a younger sister, Koko, an Irish twin (If you don't know what that is, it's when two siblings are born within a single year of one another) and they begin school at U.A. together.

One thing about his sister is that she has the quirk of both their mother and their father. She has skin that boils and the breath of fire, meaning no one can touch her, from her father, and she has the strong telekinesis from her mother.

After beginning at U.A, the lot of them get into some strife, causing Koko to be knocked down and the hero Deku to stand up and fight harder

This may change as I write and I am planning on puttin some BakuDeku in here
