This is the story of a man who exudes evil charisma. A young man living in modern Japan suddenly finds himself reincarnated in the fantasy novel he loves to read, "The Tale of Rainana." He then discovers that he is Absolute Ark, famous as the "villainous marquis" in the story. At first, he is happy to be reincarnated into his favorite work, but when he remembers that he is destined to be defeated by a hero, he takes action to change the predetermined scenario by becoming the strongest "evil" and carving out his own future.
