“Demon King, please save the world!”
Gaius, a demon king, was asked this by a human princess.
“Huh? You’re human, and you’re asking a demon king to save your country?”
“Yes, Demon King. If you’ll help us drive back the demons and free humanity from the flames of war, I’ll offer you everything I have!” the girl pleaded sincerely.
“I can save the world that belongs to humanity, but you must make a contract with me!”
“I’ll agree to any contract!” The girl’s gaze was unwavering.
Gaius nodded in satisfaction and took her hand.
“Excellent! Become my blade and kill the other six demon kings!”
And so, the girl set out across the continent on a journey to hunt down the demon kings, with a demon king at her side!
