If any anime character was your biological sibling, who would it be?

Tetsuya Watarigani from metal fight beyblade ^_^

I'd like to think it would be ether Lain Iwakura from Serial Experiments Lain, of Misuzu Kamio from Air.

In Lain's case it would make sense, since we're so much alike, and Misuzu would just make an adorable little sister.

Misuzu Kamio :)

Most definitely Maka Albarn. Our personalities literally hav nothin diff. I even chop people. And also i have my own Soul, Black ster and Tsubaki. It's most definitely Maka. Cuz i look up to her like a sister already. She's amazing!!!! Whenever I roleplay Soul Eater with my BFF, Maka is always my sister
