This is the one that turns a high school turf war into a blood feud with swords, and it never once blinks at how ridiculous that is. Kurumada's DNA is all over it: martial arts academies as battlegrounds, a rival school poaching talent like it's a crime syndicate, and a ninja clan summoned in like artillery because Himeko Hojo refuses to let Hakuo Gakuin die quietly. Kojirou shows up grinning while everyone else is panicking, and the Yasha clan hits back with the kind of named-attack theatrics that only work if the animators fully commit. This is 1990 OVA budget doing what TV never could, hand-drawn impact frames, held reaction shots, blood that actually lands on the frame. If you grew up on Saint Seiya and wanted it with katanas and a school uniform, here you go.
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.
