The teacher of the girls ping pong club (Mr. Tachikawa) tricks the teacher of the boys club (Mr. Shibazaki) into giving the training room to the girls. The boys are not happy with this and fight back to reclaim the training room with some devious tricks of their own.

The boys without a training room of their own, end up picking up trash in the schoolyard. Takeda and Kinoshita get invited to play with the girls but the other boys are left out. In the end Mr Tachikawa takes pity on them and lets the boys club play a match against the girl to win back their training room.

After losing the game to win back their training room, the boys go about to find Mr. Tachikawa's weakness. After finding out that he has a crush on Miss Tachibana, the boys plan to make a sexy video of her so they can strike a deal with Mr. Tachikawa.

A girl suddenly comes to the training room asking for Maeno. She tells him that she likes him but Izawa, jealous of Maeno, ruins any hope of a relationship. Maeno vows revenge on Izawa. The next time a girl comes to the training room asking for Izawa, Maeno is ready for some revenge.

Mr Shibazaki get a new manager for the club. It turns out to be a girl that Takeda knows from his childhood, Kyoko Iwashita. A few days later they get the news that they have to play against the favorite in the coming championship. Kyoko thinks of a plan to motivate the club.

The team discovers that Maeno has used the remainder of the club's new ping pong balls for a very non-ping-pong-related purpose. The team pools money to purchase new balls and uses paper-rock-scissors to select who will actually go and make the purchase. However, Izawa expresses concern as Maeno was the one randomly selected.

It's the height of summer, and very hot. The club decides to go for a swim in the school pool. The captain of the girls swimming team lets them in, but has ulterior motives.

The underfunded ping pong club was forced to join the baseball team's training camp last year, but ended up being ball boys. This year, Mr. Shibazaki tries to make amends by bringing the boys to an inn in the mountains for their training camp. The inn is owned by Mr. Shibazaki's friend, Mr. Uehara, who happens to be a monkey. However, the inn seems to have more facilities for baths than ping pong.

While at the inn, Takeda wakes up in the middle of the night from a nightmare only to come face to face with the ghost of a woman confuses Takeda with her former lover, Yaguchi. According to Uehara, Takeda is the spitting image of Yaguchi, a man who had intended to commit double suicide with the woman, but chickened out. Takeda decides to make a trip up the mountain and offer incense to the ghost.

The club decides to have some fun watching college girls at a public swimming pool when Mr. Shibazaki arrives on a bicycle and offers the boys a chance to play ping pong against ""grown-up girls"". The boys happily accept, but the Beauty Mamas are not quite the ping pong club the boys expected.

The boys seem to have lost hope of winning their upcoming tournament, but Kyoko offers them an incentive they can't ignore. Reinvigorated, the boys practice harder than ever. But when Maeno plays poorly against Kyoko, who is just a ping pong beginner, Kyoko accuses him of dragging the rest of the team down. Humiliated, Maeno decides to enlist the help of Mrs. Kishimoto.
