Haruka Sakura, a delinquent high school loner, admires strength and disregards weakness. Enrolling at the infamous Furin High, he aims to become the top fighter among 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 gains notoriety for its fierce fighters. Angered by Sakura's words, Kyotaro Sugishita lashes out, sparking an intense brawl between them as Hayato Suo observes coolly, and Nirei panics.
Rival factions Bofurin and Shishitoren clash, with Bofurin protecting middle schoolers. Sakura gets a war declaration from Jo Togame, Shishitoren's second-in-command. She informs Umemiya, along with Toma Hiragi, a Bofurin Four King.
"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 expel their defeated teammate. Sakura is shaken by this, but Suo gets emotional and defeats Minoru Kanuma, securing another win for Bofurin.
Resumed the showdown between Sakura and Togame. As the former confronted the latter about losing his fire midway, Togame dove back into his memories of the past.
Fierce high school rivals Umemiya and Tomiyama engage in a decisive one-on-one battle, with Tomiyama seeking to claim Furin High School, freedom, and an unparalleled sense of fun as the victor.
Admitting defeat, Tomiyama offers Shishitoren to Umemiya, who suggests being friends instead of taking over. Bofurin and Shishitoren are stunned but agree, sharing food and celebrating together.
After the battles against the Shishitoren, things start to calm down for Sakura and his friends. Upon returning to school, they meet Tsugeura, who invites them to talk at a restaurant. But suddenly a colleague arrives accompanied.
Second-year students Ren, Yuto, and Takeshi from the Tamon Team hold a vote to decide the Grade Captain for first-year Class 1. Suo nominates Sakura, and the other classmates follow suit.
