Haruka Sakura was ostracized from a young age because of his unusual looks and poor social skills. Yet, this harsh treatment forged him into a skilled fighter, which is now the sole source of his pride. Enrolling at Furin High School, a place rumored to prioritize strength over academics, Sakura has just one objective: to claim the top rank. On the day before his enrollment, Sakura gets caught up in a street fight and encounters a group of future classmates. Rather than facing the usual rejection, they join him in the battle, revealing that the school's true priority is safeguarding the town of Makochi from danger—this is why the students refer to themselves as "Bofurin." Taken aback by the townspeople's support and appreciation, Sakura struggles to accept their kindness. Unaccustomed to being treated with kindness, Sakura must overcome his discomfort as Bofurin faces powerful adversaries. Having experienced acceptance, he finds himself fighting for others for the first time.
