What's on your mind?
Arata, a student at a private high school, often spends his lunch breaks in the corner of the library.
One day, a female classmate comes to him for advice.
"I want you to help me find my lost commuter pass."
Starting with that event, various consultations begin to be brought to Arata. Centered around Chikage, they solve one mystery after another within the school.
Arata doesn't solve police-level crimes, but rather the "small mysteries of high school life."
