Kirikaze was an Iga shinobi and a loyal follower of Akame of the Iga Clan.
Kirikaze is a solid white Kishu-inu. In the Ginga Nagareboshi Gin anime, he is more grey in colour, and has lighter dots over his eyes. He has small pupils.
He seemed to be close with Jinnai and loyal to Akame.

Later, he goes with Jinnai, Akame and Gin to get healing herbs from the Kouga territory. When Akame stays alone to fight the enemy in order for the others to escape, he almost breaks the order as he doesn't want to leave his commander to die.
After the death of Kurojaki and the Kouga dogs, the remaining Iga dogs, including Akame, Kirikaze and Jinnai joined Gin's pack. Unfortunately, Kirikaze didn't live to experience the final battle against Akakabuto as he was killed by the bear Madara when he tried to save Jinnai from his certain death.
