Renzou Kawakami

Son of Itto-Ryu member Araya Kawakami. Rin befriends him, only to discover his father was the one responsible for raping and then killing her mother. She and Manji orchestrate a scene where it appears that Manji murdered Araya in cold blood and then was killed by Renzo so Renzo would not seek revenge like Rin. After being orphaned by Manji, he is now working with Shira.
