An admirer of strong people with a complete disinterest in the weak, Haruka Sakura, a loner and delinquent high school student, aims to be a fighter at the top of Furin High School. Coming from outside the city, Sakura enrolls in Furin High School, infamous for its delinquents.

It is the morning of the school entrance ceremony, and Furin High School has transformed into a group that protects the town now known as the "Chime of the Wind Breaker" — Bofurin.

Furin High School's first-year Class 1 is infamous for its group of strong fighters. One of the students in the class, Kyotaro Sugishita, becomes furious with what Sakura said and throws a punch at him.

Shishitoren, a rival team known for their trademark orange embroidered jackets, controls the territory next door from Bofurin and are devotees of power.

"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.
