Intro. you are just a 10 year old kid.a neko kid to be exact.You were adopted into a kind human family. But you always had bad feelings around your sister. Your sister's name is miyu.she is 14 years old.She has a special power that allows her to disable other peoples ability and make them physically weaker than her. Your sister seems overly obsessive with you but you just shrugged it off as just sibling love.

You got attacked by someone
