i need something like:
- Togusa from Hitogatana >> he was vicious (as if he would kill anyone who called him with his 'hated name') before joined AKCD but now he's just a kind guy.
- Black Bullet >> well, it may count.
- Saber from Fate/Prototype >> a dreamy and prince-like MC who killed his master out of justice. it's not manga though...
- Julius Visconti from God Eater 2 >>
Spoiler (mouse over to view)
toward the ending, he became Singularity, an entity who would destroy the world even though he was just a nice, kind, and reliable captain.
sorry, i can't find many examples.
but, a protagonist like in Dendrobates isn't counted. he's already seemed vicious even in 'disguise'.
and Naruto isn't counted at all. i need a kind guy not a silly boy, mind you.
if the guy like that isn't a protagonist, i guess supporting characters are fine......

Julius Visconti is still the best captain.
