Makina Hoshimura, a deceased teenager, is given her first mission to eliminate dead corpses on Earth. Her target is Hagino, a criminal accused of killing women, who came back from the dead as a vampire corpse.

After several children killed in a highway accident come back to life as corpses, Makina is dispatched to kill them. However, Ouri Kagami gets in the way when one of them pleads to him to help her escape. Keisei and a band of anti-corpse monks assist Makina to take down the child corpses.
