Plot

The hero Max and his party slay the Demon Lord. Ten years later, the Demon Lord resurrects, but now looks like an androgynous young boy. Eager for a rematch, the Demon Lord tracks Max down, only to find that after being rejected by society, he has become an unemployed slacker who lives in a one-room apartment. The Demon Lord decides to move in with him and try to get him back into shape so that they can have their rematch, much to the frustration of the Demon Lord's secretary, Zenia.

Characters

The legendary hero that struck the final blow against the Demon Lord ten years prior, Max grew intoxicated from fame and fell from grace. He retains most of his physical strength and mental acumen despite his slovenly appearance, although he has also become jaded over the paths his friends and humanity in general have taken.

The very Demon Lord that threatened the world. After reincarnating, he personally seeks out the man that defeated him. Once he discovers the state Max is in, he vows to train Max back to the status of a hero for their inevitable rematch.

The Demon Lord's voluptuous and fiercely loyal personal secretary. She makes up for her lack of magic ability with immense physical strength. After discovering where the Demon Lord went, she moves into the apartment next door to keep an eye on them.

The cleric of Max's party who has since risen to the position of the Chief Secretary of the Kingdom's Magic Bureau. A former conman despite his strong magic abilities, Fred is easily angered and also not above using emotional manipulation and blackmail for his own personal gain.

A physically powerful fighter and one of Max's former party members, he had allegedly defected from the Kingdom sometime after the Demon Lord's defeat to set up his own "republic", leading it to a measure of prosperity but earning the ire of his former allegiance - and his former partner - in the process.

The wizard of Max's party who hid her genuine concern for the party's wellbeing out of pride and a personal sense of competitiveness. She retired and also disappeared from the public eye after the Demon Lord's defeat.
