In "Katsu!", 15-year-olds Satoyama Katsuki and his best friend Kawakami Kyouta join Mizutani Boxing Gym to get closer to their crush, Mizutani Katsuki, the gym owner's daughter. Satoyama learns that Mizutani has a tense relationship with her father and strongly dislikes boxing. However, during a training session, everyone—including Mizutani—notices that Satoyama possesses natural but untapped boxing talent. Satoyama later discovers that Mizutani actually loves the sport but resents it because of its male-dominated environment. She becomes his trainer and manager, aiming to turn him into a champion. Satoyama agrees, hoping to strengthen his connection with her. As the story unfolds, it is revealed that Satoyama carries a hidden heritage and background that grant him the innate ability and talent to become a renowned Oriental professional boxer.
