During the late 1990s, Japan experienced a disturbing wave of suicides that caught widespread attention due to their eerie similarities. Each victim had thrown themselves from the towering Fujou building, a looming abandoned structure that cast a shadow over the city. Shiki Ryougi, a girl with supernatural gifts and a stoic demeanor, resided alone and was convinced that supernatural forces were at work in these tragedies. To solve the mystery, Shiki enlisted the help of Touko Aozaki, a doll-maker turned detective with magical abilities, and her capable assistant, Mikiya Kokotou. As they delved deeper into the perplexing case, Shiki uncovered a horrifying enigma that shed light on the anomalous phenomenon haunting Japan's streets.
