The animation series' tenth installment begins. A second moon appears in the sky, its red glow heralding the Demon Lord's return and empowering the demonic forces. Leona, a warrior on a mission to defeat these rampaging demons, faces increased difficulty confronting them. She is rescued during a battle by Hein, a researcher investigating methods to counter the demons. He claims to possess a way to defeat them despite the power granted by the red moon. This method requires Leona to surrender her body to him, a condition she initially resists.
