Burgund Haneiyuutan

Decades ago, demons led by a "Demon Lord" nearly destroyed the land of Burgund, but were supposedly defeated by the "Heavenly Knight," a hero who restored peace. However, the reality is more complex. At the Juvren Knight Academy, the underperforming student Shun has a father known as the "Heavenly Knight" and a mother once called the "Demon Lord." His sisters possess dangerous ambitions and extraordinary strength, pushing the world toward destruction. Determined to restore harmony within his family, Shun, despite his weaknesses and status as a dropout, resolves to become a hero to protect what matters most.
