1 - Dear Sister of Mine

So, Bakugou Katsuki has a little sister.
Bakugou (Y/N), five years old and her hero is her big brother. (All Might too, but that's besides the point!)
This is (Y/N)'s adventure as she makes her way through life as the youngest Bakugou.
Have I mentioned that Class 1-A will officially/unofficially make her the class's little sister?
(Will loosely follow BNHA/MHA storyline)
