Zacken always thought if he ever got summoned, it would be by a beautiful human princess begging for his heroic powers. Instead, he ends up standing in front of… a pint-sized Demon Queen who can barely reach the summoning altar.

Now stuck in a demon empire that’s falling apart—generals dead, council meetings going nowhere, and everyone panicking about the hero party—Zacken finds himself cast in the weirdest role ever: part babysitter, part “strategist,” and part scapegoat for every bad idea.

Between a paranoid council that argues more than it plans, magicians that may or may not know what they’re doing, and a Demon Queen who insists he’s her “secret weapon,” Zacken has to figure out if he’s the chosen savior of demons… or just the universe’s punchline.
