Ryouko Ookami is a tough, athletic girl who serves as the enforcer for her school club. The Otogi Bank functions like a real bank, granting requests to students and expecting a future favor in return. Even though it may seem strange for a high school club to need a fighter, Ryouko is their girl. Sixteen-year-old Ryoushi Morino, who is shy and introverted, becomes a surprising addition to the club after confessing his love for Ryouko. Throughout Ookami-san to Shichinin no Nakama-tachi, the Otogi Bank members deal with a variety of requests that range from boring to perilous. Although Ryoushi wants to impress Ryouko, she doesn't believe he can handle himself in a fight due to his issues with being seen by others.
