The Celestial Maiden's Bestial Path

A Japanese folklore-inspired visual novel about two celestial sisters, Nanao and Yuao, who come to a remote mountain hot spring to bathe. After removing their enchanted feathered robes—the source of their power—they become vulnerable. A beast-like demon monkey dwelling in the spring captures them and subjects them to sexual assault, with H-scenes animated in Live2D. The story explores their corruption and transformation as the weaker sister falls under the demon's influence, leading to a dark conclusion where the elder sister also loses her freedom and any hope of returning to the heavens.
