The intense rivalry among the Kanto high schools escalates further with the dragon awakenings of Kyousho and Seito Academy leaders Moutoku Sousou and Gentoku Ryuubi. However, the power balance between these two schools and their primary rival, Nanyo Academy, is threatened when Shimei Ryomou acquires a mysterious dragon orb in China. The orb is said to grant power to its dragon wielder, and Shimei hopes to use it to save Nanyo Academy's leader, Hakufu Sonsaku, from the adverse effects of her unstable gift. Meanwhile, Moutoku's powers completely consume him, and he loses control of his body to the Demon King's soul, whose boundless ambitions endanger regional stability and the safety of his allies. Amid growing tensions over the dragon orb, Hakufu and Gentoku must set aside their differences and cooperate to thwart Moutoku's demonic schemes.
