A series of eerily similar suicides occupy newspaper headlines in late '90s Japan. Amidst all the bizarre resemblances, there is one detail that stands out above the rest: the victims have all taken their lives by leaping from the Fujou building, a run-down abandoned structure rising high above the city.

Shiki Ryougi, a cold-hearted girl living in an empty apartment, suspects that these sinister events have a supernatural cause. Possessing a mystical power herself, Shiki works to investigate the incidents alongside Touko Aozaki, a doll-making detective specializing in magic, and her friend Mikiya Kokotou who works as Touko's assistant.

Shiki unravels the mystery as she ventures through an enigmatic world to uncover the dark secrets surrounding the strange phenomenon.
