The Tsundere Demon King Won't Give In, Even as a Maid

[Absurd, hilarious transformation power fantasy + playing weak while hiding one’s strength + System golden finger + everyone’s favorite + bickering couple]

Wu Jingcen, once a great demon king who dominated his corner of the world, is betrayed by his former best friend and the son he painstakingly raised. Unwilling to accept his fate, he vows that if he ever gets another chance at life, he’ll tear off their disguises and reclaim his throne.

It seems Heaven hears his final wish and gives him a chance to start over!

But… who is this fair-skinned, beautiful woman in the mirror? And why is he in his sworn enemy’s home?

The Goblin King is reborn: a growth story about a tsundere little maid who goes from playful and adorable to a domineering, scheming empress.

The story focuses on the protagonist, with a little ensemble cast flavor.
