■Synopsis High school freshman Mizui Sakaitaro is approached by his friend Takano Hijiri, who tells him that his ex-girlfriend, Kagami Kiyoka, has cursed him to death. To investigate, he visits the Occult Research Club, where Kagami Kiyoka is a member, and meets Utsugi Riyo, the club’s president. Riyo is a mysterious girl rumored to be “cursed.” Riyo asserts that true supernatural phenomena are those that cannot be explained or disproven! Together, Sakaitaro and Riyo investigate the authenticity of ghost stories posted on a message board.

https://note.com/mpent_book/n/n7a92a5d36087 ■ Mystery writers express their astonishment one after another! Today, Riyo Utsuki solves ghost story mysteries. In order to encounter the “real thing”! The great detective is not even allowed to dream of supernatural events. A brilliant blend of original horror and meticulous deconstruction. We can’t wait for the sequel! –Author Itsuki Yu The seniors in the Occult Research Club are always cute. However, this work has so much to offer that it would be a shame to bury this review in myths about the characters. The high school youth, the occult research, and the story’s theoretical unravelling of these mysteries are all enjoyable to read. And Utsugi-senpai is, as always, cute. –Author Shibata Katsuie Don’t just let ghost stories scare you! The detective in this work unravels the truth behind the ghost stories that circulate around town, as well as the history and human psyche surrounding them. It’s exhilarating to see him examine ghost stories from every angle and unravel a timeless mystery. A horror mystery with connections to folklore. ――Writer Suikage Tsukisei ■Author information Kusei Togudo Born and residing in Chiba Prefecture.
