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, o 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 stella, star 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
