[Keiki] Fallen Priestess Yuri (2D Comic Magazine Inmon Akuochi Kairaku ni Yotte Seigi o Uragiru Bishoujo-tachi Vol. 3)

Priestess Yuri and her swordsman partner Alus make a deadly monster-hunting team, until a goblin ambush leaves her at a beast's mercy with a degrading bargain: use her mouth or surrender her virginity and her life. What starts as reluctant survival quickly spirals as she takes the creature again and again, a demon seal burning into her skin and rewriting everything she once believed in. By the time a human city burns, the once-devout healer stands reborn with pointed ears at her new demon master's side, her partner left hollow in her wake.
