A Hero in the Demon's Castle

Finished

勇者IN魔王んち

Wisped is an immortal and all-powerful Demon Lord who has grown weary of his eternal solitude. His daily life consists of fending off heroes who come to challenge him, but his heart remains empty. One day, a cheerful and unarmed hero named True arrives at his castle, laughing instead of preparing for battle.

To Wisped's surprise, True does not attack. Instead, he asks an absurd question: could he live in the Demon Lord's castle? This unexpected request sparks the beginning of an unusual relationship between the lonely demon king and the friendly adventurer, blending comedy, fantasy, and budding romance.
