In September 1998, taciturn Shiki Ryōgi lives alone in a barely-furbished apartment where she is routinely visited by a close friend, Mikiya Kokutō. One day, he visits her and offers Shiki strawberry-flavored Häagen-Dazs ice-cream. The two engage in friendly banter.
Later, Shiki discusses a series of suicides involving several high school girls with the magus Tōko Aozaki, head of Garan no Dou (伽藍の堂, Hollow Shrine), a detective agency (of which Shiki and Mikiya are employees) specializing in paranormal occurrences.
