The Everyday Struggle of a Retired Demon King Novel

Once a terror among demons, commanding legions and waging wars without end, the Demon King has finally hung up his crown for a simpler dream: living an ordinary life in modern Japan. That plan crumbles instantly when dragons intrude, angels meddle, and a barrage of supernatural classmates refuse to leave him alone.

Conquering worlds proved easier than surviving high school. A millennia-old demon lord discovers that fitting into teenage society presents challenges far beyond any battlefield conquest.

This crossover mashup pulls from Gabriel DropOut, Miss Kobayashi's Dragon Maid, Saekano: How to Raise a Boring Girlfriend, Love, Chunibyo & Other Delusions!, and Anohana: The Flower We Saw That Day—following an ancient powerful being's desperate struggle to achieve what should be achievable: a completely unremarkable existence.
