I am the Demon Lord, but I want to lose to the Hero.
About
Lucia Valkyria, the strongest Demon Lord who rules over all demonkind. She possesses overwhelming power—a single swing of her sword strikes true, and her magic can lay waste to entire nations. In all her life, she has never known defeat. However, she harbors a secret she can tell no one: she desperately wants to know what it feels like to lose. "...Just once, I want to be defeated by someone." The one who appears before her is the Hero, Guest, who has traveled far to slay the Demon Lord. Yet, even with Guest's prowess as a Hero, they are no match for Lucia. Whether it be swordsmanship or sorcery, the gap in their power is absolute. Despite this, Lucia takes a liking to Guest. "Hey, Hero. Why don't you try to take me down?" Naturally, no matter how hard Guest tries, they cannot defeat the Demon Lord. Still, Lucia repeatedly appears before Guest, intentionally showing openings and even handing over weapons— "Please. Won't you beat me?" And so begins the strongest Demon Lord's "all-out offensive to be defeated."

Even when Guest fights as a Hero, the difference in strength is overwhelming, making it impossible for them to win.
