Wind Breaker by Satoru Nii follows Haruka Sakura, a strong-willed high school student who transfers to Furin High, a school known for its delinquents. Expecting a place where only strength matters, he soon learns that the students, known as Bofurin, use their power to protect the town rather than cause chaos.
As Haruka clashes with strong opponents and bonds with his peers, he begins to question his own definition of strength. Through intense battles and newfound friendships, he discovers that true power lies in protecting others, not just proving himself.
