Haruka Sakura tiene un aspecto peculiar y siempre lo aislaron por ello, pero espera que las cosas cambien en su nueva preparatoria. No obstante, luego de mudarse ayuda a una mujer que cambiará su visión del mundo.

Sakura conoce a un torpe estudiante de la Furin, Akihiko Nirei. Luego de una nueva tanda de problemas, Akihiko y su nuevo compañero se adentran en la que será su nueva clase.

Después de llegar a la escuela, Sakura sale con Hiiragi y sus nuevos compañeros a patrullar el barrio. Ahí se topan con una banda rival y nada bueno saldrá de ahí.

A fight breaks out between Bofurin and Shishitoren as Bofurin tries to protect the town's middle schoolers. Sakura receives a declaration of war from the group's second-in-command, Jo Togame. Sakura and one of the Four Kings of Bofurin, Toma Hiragi, tell Umemiya what happened.

"That’s why I'm going to take all of Furin…and you for myself!" declares Shishitoren's leader, Choji Tomiyama, as he makes his way onto Furin High School grounds. Finally, it's a one-on-one showdown between Bofurin and Shishitoren!

Tomiyama and Togame, far from worrying about their teammate who lost the battle, expel him from their team. While this peculiar spectacle shakes Sakura and the rest, Suo becomes unexpectedly emotional and wins against Minoru Kanuma, earning another win for Bofurin.

Togame can no longer hide the fact he's feeling lost. He remembers when he met Tomiyama, the fun days he had with Shishitoren, how the team changed when Tomiyama became the leader, and the things he's done himself.

It's now time for a one-on-one fight between Umemiya and Tomiyama. Tomiyama believed that by winning against Umemiya, he would obtain Furin High School, freedom, and a sense of fun that would rival no other.

Admitting defeat, Tomiyama tries to pass Shishitoren on to Umemiya — to which Umemiya declares, "Instead of taking over your team, we'll be friends!" Bofurin and Shishitoren are dumbfounded at this turn of events but talks progress, food is brought, and a celebratory afterparty starts.

With the fights against Shishitoren over, Class 1 enthusiastically welcomes Sakura, Nirei, and Suo's return. Their classmates, brimming with interest in the details of the fights, surround them, asking questions. Sakura can't hide his bashfulness.

Ren Kaji, Yuto Kusumi, and Takeshi Enomoto, second-year students from the Tamon Team, start their ruling on who will be Grade Captain for first-year Class 1. Suo is the first to raise his hand, immediately nominating Sakura as the other classmates vote for him one after the other.

Sakura, Nirei, and Suo finish their meeting with Umemiya, the other members of the Four Kings, and other prominent leading figures and join up with Kiryu and Tsugeura on their way home.
