Even the cool guy who emits an inaccessible aura had a partner who was not good at it. That is Yuzuha Komachi, a genius high school girl detective writer who is a pettanko but a hot seller. For some reason, they belonged to the Mystery Research Department of Guilinkan High School. One day, Keiichi and Komachi were involved in a strange incident when they saved Ruriko Makabe, a beautiful lady, from an accident.

A comical mystery where a stray combination that does not mesh at all challenges a mysterious mystery!
