Haison Shoujo ~Ayashi Madohi no Kago no Sato~

Hidden in the depths of the mountains lies the legendary Himeyoshi Village.

When Yakumo Itsuki and his female clubmates set out to find it, they expect nothing more than a fun adventure to break up their ordinary lives. Instead, they find themselves trapped in what appears to be the village from the tale—a maze of abandoned houses wrapped in an unnatural mist that prevents escape.

As days unfold in this forsaken settlement, a disturbing transformation begins. Itsuki notices his companions acting strangely, caught up in forbidden pleasures, their moans echoing through the ghostly village. Even he isn't immune to the village's dark influence, as unsettling desires creep into his dreams.

Into this haze of corruption steps Kagome, a mysterious maiden who presents them with a chilling ultimatum: one must stay behind as a sacrifice, or none can leave. Refusing to abandon anyone, Itsuki desperately searches for another way out.

Nonetheless, their fate hangs by an ever-thinning thread as the village's influence grows.
Will they break free from the village's corrupting grip, or will their souls be forever claimed by its dark embrace?
