The Demon King and the Hero Have Become Outdated

Igusa, a youth yearning for evil, is summoned to a fantasy world from Earth as the Demon King. Lime, a girl who despises justice, is summoned to a fantasy world from Earth as the Hero. The world these two, who desired a world where swords, magic, and a Demon King and Hero would clash, were summoned to was――― The star that the Demon King was supposed to destroy had long since perished from reckless development. The people the Hero was supposed to protect had abandoned the planet and now live in space. Humans who had long forgotten both swords and magic were actively waging wars in space. The Demon King and Hero, whose reason to fight vanished in an instant, begin to live vigorously in an SF world with "space" attached to the fantasy world they had been hoping for. Don't underestimate fantasy magic! (Demon King's account) I won't let you forget sword fantasy either. (Hero's account) A SF × Fantasy life brought to you by a Demon King and Hero left behind by the times. ※Irregular updates.
