Joined by Kobayashi and Hashiba, Akechi solves the crime committed in the exhibition hall on Panorama Island. After coming back from the island, when Kobayashi and Hashiba stop by the office as usual, Akechi starts telling them about his past.
The story takes place at a certain middle school where several murder cases take place.

Kobayashi takes an interest in Akechi and, in spite of his friend Hashiba's worries, he volunteers to be Akechi's assistant.
