The nights of Tokyo are disturbed by mysterious deaths involving the 'Reborn Dead', people who disappear at night and suddenly reappear during the day as a corpse. Also, as corpses are sent to the morgue to be autopsied, they disappear again leaving signs showing that they escaped themselves.
To fight these 'Reborn Dead' and to prevent more deaths, mysterious transfer student, Tatsuma Hiyuu, and delinquent student, Kyouichi Houraiji, stay up every night to fight the demons and discover the cause. They are joined by rest of the final year students at the Magami Academy who all have supernatural powers. They must fight not only the demons, but the powerful beings controlling them who are bent on destroying the city and the people within it.
