Any left-handed anime characters anda know of, post 'em here!!

Mio from K-ON!
She's a left handed kind of girl that plays the bas, bass and write with her left hand

Alice~ ^_^

I'm not sure if he's actually left-handed, but in his famous potato chip scene, Light Yagami says:
"Just watch me, L. I'll solve equations with my right hand, and write names with my left."

So I'm guessing that he's ambidextrous, since this implies he can write with both hands, so he's left AND right handed.

gin is left handed

Hayakawa Ryo-chan from Princess Nine!,she's a left handed pitcher,if that counts!

Shunsui from Bleach is ambidextrous.... so he is technically left handed because he can use both of his hands equally well. ^-^

These two bishies are both left-handed; Echizen Ryoma and Tezuka Kunimitsu
