Kirisame

is a missing-nin from Amegakure in the Naruto OVA Special #2.

Personality
Kirisame seems to be a bit unhinged, eagerly anticipating the attack. Suien has to remind him not to kill too many people.

Plot overview
He helped Suien attack Takigakure to take its Hero Water. He was the one who attacked Shizuku and Himatsu's mother outside Takigakure. Kirisame was defeated when Shibuki drank the Hero Water to fight back against him and his fellow attackers. His status after that is unknown.

Trivia

 * His name acutally translates to Mist Shark or Foggy Shark.
