Demon King: Are You Worthy of Being a Magical Girl?

Ye Yun is the most miserable demon king in history. The clan is destroyed, the city is destroyed, the territory is on the verge of being taken back, and even the Demon King profession is still in the [inactive] state. Desperate, he activates the ancestral brave summoning array, hoping for a brave man who can split mountains and seas and reverse his destiny. As a result, the summoning array flashed with light and actually summoned a blond cat girl with white stockings who called herself a "magical girl"? Where is this brave man? This is obviously a sacrifice sent from heaven, right? The road to the Demon King's revival starts from this outrageous start?
