Noboru Yoshikawa, a student of 3rd grade and 4th grade, has come in and out of Onizuka's room recently. Onizuka and Yoshikawa had become game friends.

　One day, Yoshikawa is called by a girl in the same class, Anko Uehara, and her friend, and is bullied to be naked and take a picture of her lower body. Onizuka, who helped Yoshikawa jump off the roof and try to commit suicide with regret and incompetence, takes Yoshikawa and makes a ridiculous revenge on Uehara and his friends.

　Mathematics teacher Yu Teshigawara is an elite teacher who has distorted feelings in Fuyutsuki. Therefore, I don't like Onizuka, who is close to Fuyutsuki.

　Teshigawara, who wants to get rid of Onizuka from the school, decides to use the help of Mrs. Ota, an influential person in the women's group.

One day, there was a love letter with "F" and initials in Murai's shoe box.

Actually, it was a girl "Kujirakawa" in 3rd grade and 2nd class who was asked by a friend to give it to Murai. However, the initials of the Whale River are also Fuyumi and "F". I suspect that Kusano and Fujikichi are actually from Kuregawa himself, but in reality it was from Fuyumi's friend Akane Fujita.

　The south wind was a legendary female runner who was once called the "Queen of Hakosuka".

　One day, the vice-principal was furious when he learned that he had been sold a fake product in the south wind. I breathe to stop the south wind. Nanfu, who had saved money for his brother's surgery, decided to quit the school because he had achieved the target amount, but a person who was asking for an agent to arrange surgery was caught for fraud.

　With the cooperation of Kikuchi and Reimi, evidence was found that it was Ya who organized the series of incidents.

　However, Onizuka destroys Kikuchi's denunciation strategy by saying, "I can't look good if I'm a big adult and I'm trapped in a junior high school student." On the contrary, if you take all the angry third graders to a trip to Okinawa, you will get a great deal.

　Students enjoying the first day of the mobile classroom to Okinawa. However, Yoshikawa seems to be being squeezed by the apricots as usual.

　That night, Onizuka, who hadn't decided on the room allocation for the students, completed an unprecedented shared room for men and women! Unfortunately (?) Yoshikawa, who has become the same room as Kyoko, is beaten up by them on the balcony.
