Betrayed, I Reincarnated as the Demon King's Daughter

As humanity's strongest hero, Arthur never imagined that he would survive the Demon King, only to die from the betrayal of his fiancee and his closest friend.

Consumed by rage, he made a deal with the fallen Demon King at the bottom of the Abyss.

When he opened his eyes again, Arthur had become Alia, a pureblood little princess who was half succubus and half Demon King!

With delicate little horns on her head and adorable bat wings hidden behind her back, Alia gazed at her breathtaking reflection in the water and gritted her teeth. "Holy Court, I will grind you into the dust!"

To steal humanity's most vital secrets, Alia suppressed her demonic aura and enrolled as the daughter of a fallen noble in Saint Laurent Noble Girls' Magic Academy, the most heavily guarded institution on the continent.

When the daughters of her old enemies swaggered around and showed off in front of her at the academy, Alia smiled benevolently. "Magic? No. I prefer to reason with people using Abyssal Flame Burst."
