The Demon King’s Unexpected Conquest in the Modern World

The Demon King has descended upon the modern human world, accompanied only by his loyal assistant, determined to carry out his ambitious plan of global conquest.

However, his arrival does not go as expected. Instead of inspiring fear, most people mistake him for a mere cosplayer. As if that were not enough, the demon realm is suffering from its worst economic recession in 500 years, leaving the Demon King critically short on resources.

Standing in direct opposition to him is humanity’s chosen hero, Ichikawa Kyouko — a beautiful, strong-willed modern girl who accidentally wields the legendary sword that marks her as the destined warrior.

Blending fantasy, comedy, and modern-day action, this story delivers a fresh twist on the classic hero-versus-demon-king narrative, where destiny, misunderstandings, and everyday life collide.
