Kumiko is a girl who appears before Kyotaro, introducing herself as his half-sister. She is a highly skilled swordswoman. Kumiko wields a sword named Gekkoh, which is rumored to be cursed. Her only goal is to avenge her parents' death by locating and eliminating the man with the centipede tattoo.

She witnessed these events, but this traumatic memory had been repressed in her subconscious.
