Yuusha Party ni Kawaii Ko ga Ita no de, Kokuhaku Shitemita.

Yuusha Party ni Kawaii Ko ga Ita node, Kokuhaku shitemita. follows Youki, a man who dies in a traffic accident and is reincarnated in a fantasy world as an immensely powerful demon. Rather than chase the title of Demon Lord, he chooses an easygoing life inside the Demon Lord's castle, where he works as a low-rank guardian and spends his days idling among monsters and villains with little ambition beyond staying out of trouble. That quiet routine changes when the Hero's party raids the castle. On a whim, Youki defeats the entire group, heals them, and prepares to send them back to town, only to have his attention caught by the female priest among the heroes. What starts as a bizarre enemy encounter turns into an awkward first step toward romance, and the comfortable rhythm of his days begins to slip away. Pulled between the demon side of the conflict and the Hero's party he should be opposing, Youki is forced to navigate a relationship that is as ridiculous as it is sincere. The result is a fantasy romance built on strange timing, a peaceful castle life, and the growing tension between duty, curiosity, and unexpectedly genuine feelings.
