Is there an 아니메 character 당신 think is crazy?

Yuno from Mirai Nikki x_ô

Belarus ( To the right in the picture ) basically defines overly attached.

hichigo - bleach............
(he is the craziest & coolest character i know)

Hmm..I'd say Dark Marik from Yu-Gi-Oh! could be considered as crazy..especially with what he wanted to in the Japanese version of the anime..(won't say it because I don't want to give it away)..but it's very serious ._. and besides this face says it all..

Tamama from Keroro Gunso (When he's not being all innocent)

Is all of them an appropriate answer?....And if not Finian.

Accelerator!
well... now that I think about it, every Level 5 has their own mental defect but I choose him XD

Maria from Witchblade.
