Wind Breaker is a Japanese manga by Satoru Nii that blends high school delinquent action with strong themes of justice, friendship, and fighting spirit. The story follows Haruka Sakura, a powerful and fearless first-year student who transfers to Furin High School—a school known for its fighters who protect their town. Initially only interested in proving his strength, Haruka gradually connects with classmates like Hayato Suo, Kyotaro Sugishita, and others in the Boufuurin group, learning the importance of using strength to protect rather than dominate.
