A busload of girls from an all-girls school is on its way to Kanenone Gakuen for a month-long trial run of integrating the two schools. At Kanenone, Yuusuke leads the boys in preparing a welcoming party, with the Baka Trio acting as lookouts. Once the bus finally arrives, Midori leaps out, knocking Yuusuke unconscious in her excitement over finally meeting him, and declares that they will change their fate "this time".

The girls are dismayed at the antics of the Baka Trio and the spartan facilities at Kanenone, but are cheered up when they discover the place boasts an outdoor hot spring. The Baka Trio decide to peep on the girls as they bathe, while Yuusuke takes it upon himself to stop them.

Outraged over a prank pulled on her by the Baka Trio, Futaba decides to leave Kanenone for home. In her search for a short cut to the bus stop, she gets lost in the surrounding forest and injures her ankle. Yuusuke, Midori, and the Baka Trio attempt to find and bring her back to Kanenone.

Futaba realizes she is starting to develop feelings for Yuusuke. Midori notices this and confronts Yuusuke about Futaba. That evening, the Baka Trio (and a reluctant Yuusuke) attempt to break into the girls' dormitory while the girls are asleep.

Sanae misplaces her medicine box, but Yuusuke helps her find it. His good deed is seen and misinterpreted by Reika, who decides to try to bring the two together; and by a jealous Tazio, who enlists the help of the other members of the Baka Trio to come up with a way to win Sanae's heart.

"A Steamy Time in the P.E. Equipment Room" Midori and Yuusuke are assigned to scout for locations for a school affair. Midori decides to treat the assignment as a date, and gets Reika to promise not to interfere. In order to prevent the Baka Trio from getting in the way, Reika locks them inside the PE storage room, where the heat soon causes them to have vivid hallucinations about the girls they desire.
