Demon Curse of the Hunter

Ethan, the youngest heir of the Hunters' Order, carries a demon-blood curse. His mentor tells him that breaking it means finding three women who once fought beside him: a cold, elegant CEO, an underground fight queen, and a scheming actress, then sleeping with them. To stay alive, Ethan is forced to leave the mountain and enter a city adventure that's both life-saving and dangerously flirtatious.
