Mukuro is Koyuki Azumaya's past friend who tried to leave the ninja village. She was shocked by a ninja curse and was to fall to her possible death, when Koyuki jumped after she broke the seal and saved her. When everyone in Koyuki's ninja-village were set free, Koyuki never saw Mukuro again. The last time we see her is passing by Natsumi and Koyuki on the street wearing glasses.
Mukuro literally means corpse.
