Momiji Fujimiya thought she was just an ordinary high school student. One day, she is confronted on her way to school by a cat-eyed man with blue magatama beads embedded in his hands, who then attempts to kill her. Momiji is confused and terrified this strange man's sudden desire to kill her; he also refers to her as Kushinada, confusing her even further. Momiji is saved by the sudden appearance of two government officials, one of whom shoots the man in the arm and sends him fleeing.

 

Mamoru Kusanagi (草薙 護 Kusanagi Mamoru^?): He was given seven mitama with the expressed mission that when he was older, he would protect the Kushinada from harm. He was very close to Kaede, Momiji's twin sister, before her sacrifice in the tunnels of Tokyo. After Kaede's demise he initially goes to Momiji to kill her, in order to rid the world of the Aragami. He comes around, however, in the second episode, and from then on makes it his sole purpose to keep Momiji from harm and eventually falls in love with her. Kusanagi often pokes fun at Momiji's choice of panties just to aggravate her. Kusanagi gains his 8th mitama from Momiji when he rescues her from danger in the last few episodes, which gives him the power to fight Murakumo on an even level.
