Shigenka wa Inshi no Yoru ni Warau -Shiawase no Mura e Youkoso-

In that village, common sense turns into madness. A secret festival held once every 19 years lures them into a “happy” hell.

Amanogawa Ruri, a member of the “Regional Culture Research Club,” accepts an invitation from her close friend, Shinomiya Inori, and joins her and other club members for a summer retreat in Inori’s hometown, “Shigenmura.”

It was an isolated landlocked village that didn’t appear on any maps and had no cell phone reception. The village was about to host the legendary grand festival, the “Shigenka Festival,” which is said to take place only once every 19 years.

“In this village, happiness is something we all share.”

The villagers’ eerie kindness and their ethics, which seem somehow out of the ordinary. The sweet, mind-numbing scent of “Shigenka” that permeates the entire village. And the blasphemous rituals performed every night by men wearing laughing masks.

As their investigation progresses, Ruri and the others find themselves swept up in the village’s twisted rules. Their hearts—which they thought they had closed off—are melted by a sweet scent, and before long, they find themselves begging for “happiness” of their own accord…

Trapped deep in the mountains with no escape, will the girls choose to resist—or to succumb? On the night of the secret ritual, the deep “darkness” of the hidden village laughs at them.
