Tsugumi
Tsugumi is Sasame's sister, and the two are virtually identical except that Tsugumi has longer hair. She's typically seen dressed in a white sleeveless dress, usually appearing alongside the corpse.
Originally a priestess from Yomijima, Tsugumi ended up stranded in the Lightless Realm while the other children managed to escape—a fact that left her bitter and resentful. She's nursing a serious grudge against the group and has sworn to get revenge on IX specifically. To survive her prolonged isolation in the Lightless Realm, she's had to live off Arbornine, which has basically become her sole means of sustenance.
