Blue_assassin

I wonder if anyone could assassinate with a blade in their mouth (minus Zabuza or w/e. cuz he went beserk when he did that, I'm talking about quiet and secretive assassins xD)

So this is what I came up with: I called him blue assassin cuz when he kills, he slices the victim's throat with a blade that he holds with his teeth o_O and thus, all you see is his blue hair before you die? lol

*ahahah he DOES look like Kaito now that I compare o_O, perhaps this is Kaito when he goes evil? lolol
