In the local city of Saku Hana, a young man named Kazu lives, spending his days consumed by fights. While living with his grandmother after losing his mother, he finds himself at the mercy of a delinquent group, expelled from school, and losing the will to live. During such times, he coincidentally reunites with his classmate, who invites Kazu, who struggles to express his feelings, to a cipher, where rappers perform improvised rap. Kazu, who had lost his purpose in life, encounters hip-hop and undergoes a transformation. (Source: Natalie, translated)
