Who would あなた prefer to be your sibling(s) if s/he was/were real?

I can't really answer since I 愛 all of them so I want to marry the- Um.. Moving on.. But I'd 愛 Aida Riko to be my sister so I can watch them practice ^^; NOT MOMOI.. She's annoying to me :p

Everyone in KnB is my precious 赤ちゃん so I can't decide...maybe Aomine Daiki. He's so cool and I would 愛 to be there for him went his down and see Touou's practice with the team and Momoi. :) I will like to be witnessing the change in Aomine.

I'd 愛 to have Kuroko as a brother and Momoi as a sister.
