Kumiko Shizuki

About

Kumiko is a girl that shows up in front of Kyotaro, introducing herself as his half-sister. She is a rather skilled sword-woman. She carries a sword called Gekkoh, said to be a cursed item. Her sole purpose is to avenge her parent's death by finding and killing the man with the centipede tattoo.


She later finds out that the man she was looking for the entire time was her own father, who killed her mother and then committed suicide. She was there when it happened, but apparently, this memory was repressed in her subconscious.
