Mina cute af. Feel bad for her. Needs a friend badly. I don't get all the imouto hate in here. She's just protecting the only thing she has (her bro) from some sketchy bitches (from her perspective).
Uh, who is this Mina and why is she so adorable? Adorable introvert is like icing on an already sweet and delicious cake.
P.s Minus the incest part she is to be protected.
