About

Guest is a hero famous in the village. To stop the suffering of the people, the hero heads to the Demon Castle to eliminate the Demon King, the mastermind behind the attacks. However, the Demon King already knew the hero was coming and was simply enjoying the anticipation. The hero arrives at the castle fully prepared, but is utterly crushed by the Demon King's overwhelming power. Recognizing the hero's potential, the Demon King decides not to kill them, but to turn them into a demon and serve as her subordinate. Although the hero resists at first, their mind gradually fades away as they grow accustomed to life as a demon, eventually finding satisfaction in living under the Demon King's rule.
