AppearanceKutou is a tall and slim young man with a tanned complexion. He wears a suit with a grey undershirt and a brown tie. His most striking feature is his tattoo, which takes up the whole left side of his neck and part of his face.
He is mostly fearless and is loyal to Fumito. He is also dark and taunting. This is shown with his encounters with Saya.
Kuto appears in the beginning of the movie and talks to Fumito. He later goes to the school and fights Saya the first time. Then he appears again and gets his arm cut off by Saya (fyi he didn't care). He puts a talisman on his forehead and squeezes his severed arm to pour blood on it (quick trivia: this talisman looks exactly like the one Fumito had in episode 12 of the TV series). He then turns into an Elder Bairn and kills at least two soldiers before going after Saya. Because he is now an Elder Bairn, Saya is able to kill him.
