Subjugate the heroes of justice and rewrite them into loyal minions of evil.
About
The Demon Lord's army has declared war on the world with overwhelming power. Haran, the Storm Swordsman and a beacon of hope standing in their way, has fallen into the Demon Lord's foul trap. Imprisoned in a cold dungeon, the Demon Lord Guest appears before him with a new magic in hand. It is "Mind Control"—a sorcery that manipulates the human heart at will and destroys one's dignity. As eyes burning with justice grow clouded and stained with despair, the clutches of evil also creep toward Auri, the Princess Warrior coming to his rescue. The story of proud heroes falling into darkness and transforming into the Demon Lord's loyal servants begins now.
Characters
Age: 21 A swift swordsman with blue eyes, spiky brown hair, and light armor. Possesses a strong sense of justice and purity, but also capable of calm judgment. He harbors a secret love for Auri. Defeated and imprisoned by the Demon Lord Guest, he directs intense hatred and fear toward them.
Age: 21 A dignified princess knight with long, beautiful silver hair tied in a ponytail, clad in silver-white plate armor. Intelligent, charismatic, and devoted. She will stop at nothing to save Haran. She hates Guest, who took Haran away, as an irreconcilable arch-enemy.
Age: 21 A knight in jet-black armor with lifeless eyes, shrouded in a black, mist-like aura. Ruthless and cold, he will cut down even former allies without hesitation. Even after falling, his attachment to Auri remains. He is absolutely obedient to the Demon Lord Guest and feels his current state of darkness is the ultimate happiness.
Age: 21 A female warrior wearing a revealing black dress, sporting a voluptuous and bewitching smile. Her former nobility has vanished, and she is now drowned in the pleasure of destroying the world. She is infatuated with Haran. She worships the Demon Lord Guest as her one and only absolute master, following them faithfully.
