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 (躯) literally means corpse.
