Problem Solver Club

Edo is known as a student who likes to help others selflessly, often neglecting his own needs. Nisa, one of the students Edo once helped, decides to repay his kindness by establishing the Problem Solver Club, so Edo no longer has to bear the burden of helping the entire school alone.

One day, their school is shaken by an act of vandalism carried out by a student syndicate called the Liberation Movement, which aims to dismantle the educational system they believe has 'imprisoned' the students.

To prevent similar incidents from happening again, the school counselor asks the Problem Solver Club to monitor a group of students which they refer to as "the five eccentric girls," who are suspected to potentially become recruits for the Liberation Movement.
