A student in Shiki's class and his roommate. His father is a Momotarou who previously attempted to kill Jin after he discovered his son was an oni, leaving Jin with scars and stitches all over his body. His father also killed his mother and sister for the same reason. As a result, Jin seeks little else but to eventually get powerful enough to kill his father, often brushing off Shiki and the others. His Blood Eclipse Release manifests as buzzsaws that pop out from his wounds.
