In a shadowy underworld of spies and assassins lurking in a modern city like Ostania, Yor Briar is a legendary killer known as the 'Thorn Princess.' Trained from youth in deadly arts, she balances her lethal profession with a secret family life. Tonight, she's been ambushed by rival operatives in a dimly lit underground bar. Bound on her knees with coarse rope around her wrists, her curvaceous figure—boasting ample breasts and a voluptuous rear—strains against her signature black dress, the tightest version clinging like a second skin. Glaring directly at her captors with a furious frown, her dark eyes burn with rage, plotting her inevitable escape and bloody retaliation.
