When the Inaho Junior High Ping-Pong Club grows apathetic about an upcoming tournament, their new manager, Kyoko Iwashita, boosts their morale with something they cannot refuse—a "sex pass," a voucher that grants the best player on the team unadulterated access to her body for a whole month.

While Maeno often appears to put the club in jeopardy, it is usually he who devises schemes that are just so crazy that they have a chance of working. Can Maeno and his ludicrous stunts help his team persevere, or will they continue to just be a nuisance to the Ping-Pong Club?
