About UNDER NINJA
Thousands of ninjas hide in plain sight across Japan, living in the shadows of everyday life. One young ninja stands out for doing as little as possible, drifting through missions with a shrug and a dry wit. Then a special assignment lands in his lap and upends his routine, forcing him to weigh risk against comfort. The show drops us into a world where secret clans thread through city streets, ancient codes brush up against modern cities, and danger rides alongside humor. Expect brisk action, sharp banter, and small, telling moments that illuminate character. As the mission unfolds, nothing stays simple or ordinary for long, and choices matter.
Released in 2023, this animated series is the creation of Kengo Hanazawa and Keiichiro Ochi. The voice cast includes Taito Ban as Kuro Kumogakure, Atsumi Tanezaki as Suzuki, Tarusuke Shingaki as Kato, Tasuku Hatanaka as Miracle Hibi, and Kouichi Souma as Ozu. The visuals pair smooth action with a muted color palette that suits both quiet character beats and high intensity fights.
The show blends brisk ninja action with humor and heartfelt drama. It questions what gives a person value as it follows an underachiever who is suddenly asked to rise to the moment. Themes of purpose, loyalty, and friendship emerge as the mission reshapes his sense of self. The tone shifts between dry wit and earnest moments, keeping tension and warmth in balance.
There are no widely reported awards or nominations for this series. Still, the production has drawn attention for its stylish visuals and strong voice performances, with fans praising the balance of bite-sized humor and high stakes action. The pacing earns a thumbs up for keeping heat on while letting characters breathe.
Its premise of thousands of ninjas living in secrecy resonates with traditional folklore while offering a contemporary comedic twist. If it continues to develop, it may grow from a niche favorite into a recognizable reference for fans of anime that mix action with humor and character focus. The show invites repeat viewing as layers of the world reveal themselves.
