Kirisame

キリサメ

Kirisame is a missing-nin from Amegakure. He left his village behind to help Suien seek the Hero Water in Takigakure. He seems to be the most sadistic of the three, as he laughs while repeatedly stomping Naruto. He enjoys killing and even had to be repeatedly reminded not to kill so many people by Suien.
