[Omochi no Mochiya (Wabimochi)] Tatakau Sister ga Shokushu Monster ni Haiboku suru Hanashi (SCANMTL)

A battle-ready nun with a massive, exposed bust drives a spear into a strange-eyed monster, only to be engulfed by pulsing, eye-tipped tentacles that bind, blindfold, and reshape her body. As her combat strength fades and a tail emerges, the creature’s corruption overtakes her while a black-horned inner figure declares, “This is my true self,” urging the nun to surrender to the monster within.
