Igusa, a young man who yearns for evil, is summoned from Earth to another world as the Demon Lord.

Lime, a young girl who detests justice, is summoned from Earth to another world as the Hero.

The world to which the two, who wished for a world of swords, magic, a Demon Lord, and a Hero fighting, were summoned―――

The star the Demon Lord was supposed to destroy had long since perished due to reckless development.

The people the Hero was supposed to protect had left the star and were living in space.

Humans who had already forgotten both swords and magic were vigorously waging war in space.

The Demon Lord and Hero, for whom the meaning of conflict quickly vanished, began to live robustly in an SF world—a "space" version of the fantasy world they had desired.

We won't let you forget sword fantasy either! (The Hero)
