Time has passed since the horrific "The Legend of the Grim Reaper Murder Case" and Momoi Meguru and Tachibana Miako, the self-proclaimed head of the newspaper club, have been continuing their steady activities.
However, an unexpected person stood in our way.
Her name was Sakurada Shinobu.
She was a classmate of mine before I transferred to Konohana Academy.
She had come all the way to this school to settle a score dispute with me, and she challenged us by forming the Mystery Detective Club.
One night, a fire broke out in the basketball club room.
The fire was quickly extinguished, but Yuichiro Minami, a third-year student was inside and had burned to death...
As if to ridicule our investigation, a series of murders occur one after another.
Are these indiscriminate murders? Or is it?
Now, once again, the school is threatened by an invisible monster of terror!
