[Kanten] Haizan Senki ~miserable valkyrie~ Ch.5, 7 [biribiri]

A shrine maiden whose clan exists to fix the tension between humans and apparitions gets her purification ritual hijacked—her junior Yuuri, already corrupted into a cat-eared servant, pins her busty senpai down so the tentacled horror can break her proud body and mind. In the second tale, a curvy treasure hunter picks the wrong vault: mechanical tentacles boot up a 'slave training program' that leaves her a drooling, mooing wreck who realizes there was no treasure at all. Kanten's miserable valkries never stand a chance—every defeat turns a proud warrior into an obedient, impregnated toy for the apparitions.
