In modern Japan, rival high schools fight for power in a struggle modeled loosely on Romance of the Three Kingdoms. The three strongest are Nanyo Academy under Hakufu Sonsaku, Kyosho Academy under Moutoku Sousou, and Seito High School under Gentoku Ryuubi, each fighter carrying a magatama. Dragons have awakened in Moutoku and Gentoku. When Shimei Ryomou takes a mysterious dragon orb in China, hoping its power can save Hakufu from her unstable gift, the balance between the schools shifts. Meanwhile, Moutoku's power overwhelms him, and the Demon King's soul seizes his body. Hakufu and Gentoku must set aside their rivalry to stop him. Expect action with ecchi elements.
