There is a legend of the hidden village passed down in a certain town.
Wanted to investigate the old legend that still remains in the town where they live, the protagonist, Yakumo Itsuki, along with the female members of his club, set foot in the rumored mountains. An ordinary page of youth trip...... It was supposed to be.
"This place, where are we?"
Before they knew it, Itsuki and his friends found themselves in a strange place. Abandoned houses in the mist, stagnant air as if the time had stopped. Traces of life remained, even though there was no sign of anyone but themselves. It was abandoned by the people who once lived here, a small hidden village deep in the mountains...... The legendary "Himeka Village".
No one remembered how they got there, even if they tried to leave, they would soon be covered in fog and found themselves back in the village. They felt that they were being trapped by "something" that they didn't know. Believing that they could leave eventually, they decided to try to survive in the village.
But from that day on, Itsuki began to see his friends indulging in obscene acts. The voices of the girls he knows echoed in the village filled with sweet fragrance. Itsuki also had dreams of him raping these girls, and felt like something wicked was seeping into him.
"This place is a "Caged Village". If you are the welcomed guest...... Please, think carefully about your choice."
While Itsuki was still confused by the unusual phenomenon, a girl named "Kagome" appeared in front of him. She told him that in order to leave the village, he must choose one of his friends to remain behind as a sacrifice. Unwilling to sacrifice any of his friends, Itsuki began investigating the abandoned village, looking for a way to escape.
What fate awaits Itsuki and his friends? Will they be able to escape this abandoned village dominated by an obscene force, or......?
Is this village (cage) a paradise overflowing with pleasures or a prison bound by passions and desires――――
