I Tamed the Demon Heiress

Human slum girl Alia takes a fortune to tutor Vivian, a vicious pureblood demon heiress. Armed with anti-demon weapons and zero patience, she beats the brat into obedience—then risks her life to save her. Together they crush a poison plot, defy the imperial court, and seize the power to rewrite the laws of the Abyss. Their bond rocks demon society.
