The Reincarnated Demon Lord Dotes on the Villainess

The oldest and strongest Demon King—history records that there was once someone called by that name. The hero who accomplished what countless other heroes could not—slaying the Demon King—later spoke these words: "Be careful. That guy isn't dead." Approximately 2,000 years after that era, the Demon King returned to this land once more, reincarnated as the Third Prince of the Kingdom of Lyzen. The entertainment-loving prince then set his sights on his older brother's fiancée. This is a story of the strongest, undefeated Demon King who loves entertainment. After his reincarnation, he collapses the scenario of an otome game while falling deeply in love with her and being loved in return. ※Warning: Contains excessive doting love, yandere tendencies, and cheat-like elements. The Demon King is planned to be genuinely beyond standard specifications. Also planned to be posted on Alphapolis.
