Kojiro arrives at a school nobody cares about anymore and discovers the real fight isn't against the Yasha clan, it's against the weight of a name he never asked to carry. The Fuma ninja legacy means something, and every combat sequence proves it through pure martial craft rather than supernatural nonsense. By the final episode, you understand that this OVA exists to show you what happens when an ancient lineage has to matter in a modern world that stopped paying attention.
Hakuo Gakuin, once a martial arts powerhouse, faces extinction as its rival Seishikan systematically poaches its best students. Desperate to save the school, principal Hojo Himeko reaches out to the legendary Fuma ninja clan for help. What arrives instead is Kojiro, a skilled but unassuming warrior who quickly discovers that Seishikan isn't just playing dirty in school competitions. The Yasha clan, a group of ruthless ninjas led by the formidable Asuka Musashi, has been orchestrating the entire scheme. When Kojiro's own comrades from Fuma Village join the fight, a centuries-old conflict between two ninja dynasties suddenly reignites on school grounds. What begins as one transfer student trying to save his school spirals into an all-out war that neither side anticipated. Packed with intense martial arts sequences and genuine stakes, this OVA blends high school drama with genuine ninja warfare, creating something that feels both grounded and wildly ambitious.
