Twelve episodes with no filler, no breathing room, just Ryuuji learning to throw a hook that curves back like it's defying physics while his sister screams strategy from the corner. The boxing itself is absurd, full-contact manga spectacle where technique matters but so does the sheer will to not get knocked down. Missing chunks of the source material means you're watching the highlight reel, which sounds like it should feel hollow but instead feels like the show trusts you to keep up and rewards that trust by moving at a pace that never lets you sit down.
Ryuuji and Kiku Takane set out to win the boxing championship their late father wished for. Kiku takes on the role of trainer, while her brother Ryuuji focuses on being the fighter and learning a move called the Boomerang Hook. Bout after bout against a string of rivals helps Ryuuji grow and mature. When the junior high boxing tournament gets underway, he faces his arch-rival, Jun Kenzaki. This 12-episode action sports series is adapted from the manga by Masami Kurumada.
