Who is you best anime with a smart main char (like death note, code geass...)

Victorique de blois from GoSick of course.

Ginko from mushi-shi. Hes pretty smart. Fun series.

 

[mangge]

I will say Kotomine Kirei in both fate/zero and fate stay night #3

 

[DvorakUser]

Hmmm off the top of my head, I'd say Makise, Okabe and Hashida from Steins;Gate. Also, I'd have to include Koko and Dr. Miami (for different reasons) from Jormungand.

 

[Szacsesz]

Death Note: L and Light
Hyouka: Houtarou

Eden of The East. Akira Takizawa is quite clever
