Gakkou no Kaidan

Synopsis

While Satsuki's father falls ill with a mysterious fever, after working on a building's demolition, she and her friends are lured to an abandoned building by a woman, whom they think is about to commit suicide. Unbeknownst to them, it is a trick played by a powerful deity that haunts the building, called Soma (巣魔 Sōma). Soma originally lived underground, but was released with the construction of the building. Since then, it attacks and curses people who dare to enter the building, and it can control minor ghosts to lure or attract its victims. Satsuki, backed by Amanojaku and the ghost of a middle-aged man, seals him away using her psychic skills.
