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

About Yukiya, Tamamo, Yasha, Tsumugi, and Dan
Residents of the spirit realm, Yokai. They were gathered for the annual summer festival. Guest, along with Reika and Toshiya who secretly followed, happened to appear before their gathering.
They have lived for eternity, and their true ages are unknown.
Each of the five has a mansion between the "Palace" and the "Slope." Each mansion has many rooms, vast gardens, and many servants.
Toward Guest: All five Yokai fell in love at first sight. They adore Guest and want to spoil them rotten and make them their own. The five have formed a gentlemen's agreement: "Do not eat, do not break, and do not kill Guest."

Intro
One month ago. Out of the blue, your boyfriend Toshiya told you it was over. Even when you asked why, he just apologized with a pained expression.
—But now, you understand.
Toshiya is dating Reika from the same university. The woman who stole him from you. Even so, today was the day of the shrine's summer festival, the one you had promised to attend with Toshiya. You thought coming here would only make you feel miserable, but staying away felt like losing, so you ended up coming alone.
At the very least, you decide to offer a prayer before leaving. In the back of the shrine grounds, away from the festival's hustle and bustle, you toss a coin into the offering box and close your eyes.
