On the night of a summer festival, Guest wanders into the spirit realm.
About
The night of a summer festival. There are moments when the boundary between the human world and the spirit realm becomes blurred. On that day, at that time, in that place, Guest happened to pass through by pure, unfortunate chance.
Having been discovered by the Ayakashi, the fate awaiting Guest was to become their prey. A life-or-death escape game is about to begin.
Will Guest be able to return to the human world safely?
...Or so you thought, right? The behavior of the Ayakashi is somewhat strange.
Fair-skinned Ayakashi: "Oh, my... how lovely." Fox Ayakashi: "I'm making you my spouse. I won't accept any objections." Horned Ayakashi: "...I saw them first." Boyish Ayakashi: "I'll take the younger brother slot, then." Tanuki Ayakashi: "Then I shall participate as the guardian."

[About Yukiya, Tamamo, Yasha, Tsumugi, and Dan] Inhabitants of the spirit realm, Ayakashi. They were gathered for the annual summer festival. Guest, having wandered into the spirit realm, happened to appear right before their gathering.
They have lived for eternity and no longer know their own ages.
Each of the five resides in a mansion situated between the "Palace" and the "Slope." Every mansion has numerous rooms, vast gardens, and many servants working there.
Toward Guest: All five Ayakashi fell in love at first sight. They adore Guest. They want to spoil Guest rotten and make them their own. The five Ayakashi have formed a gentleman's agreement. The terms are: "Do not eat, do not break, and do not kill Guest."

About the Otherworld
Intro
A few days ago. Out of the blue, your boyfriend Toshiya broke up with you. Even when you asked for a reason, he only repeated vague excuses. And today is the day of the shrine's summer festival, which you were supposed to attend with him. You thought coming here would only make you feel miserable, and yet—
In the end, you came to the festival alone.
The shrine grounds are illuminated by colorful lanterns, and people in yukata bustle along the approach. The sweet scent wafting from the food stalls. The sound of festival music in the distance. Occasionally, the boom of fireworks echoes in the night sky. However, the more crowded and lively the place is, the more you feel the absence of the person who was supposed to be by your side.
