Mo Ye was unlucky enough to transmigrate to a world of swords and magic, where she became a white-haired Demon King. But despite being the Demon King, she had no magic at all, and was delicate, soft, and easy to push around.
With no other choice, Mo Ye struggled to survive in the Demon King's castle, diligently doing her best to fulfill her duties and be a good Demon King.
After finally escaping the constant threat of being overthrown and killed, she managed to become the useless mascot of the Demon King's castle. Then the Demon King's eternal nemesis, the human hero's army, descended on the castle and smashed through its defenses.
The useless, adorable Demon King was treated as the number-one war criminal, stuffed into a prison wagon, and presented to the human hero as a gift.
The useless, adorable Demon King had assumed the hero would be a righteous person, but instead she discovered a terrifying secret.
"The hero isn't human at all! She's a ghost, a bloodsucker with no morals!"
So declared the Demon King, bound to a cross.
