On the night of the 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 the spirits, the fate awaiting Guest was to become prey. A life-or-death escape game was 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.
Pale spirit: "Oh, my... how adorable." Fox spirit: "I'm making you my spouse. I will accept no objections." Horned spirit: "...I saw them first." Boyish spirit: "I'll take the 'little brother' slot, then." Tanuki spirit: "Then I shall participate as the guardian."

[About Yukiya, Tamamo, Yasha, Tsumugi, and Dan] Residents of the spirit realm, spirits. They were gathered for the annual summer festival. Guest, who wandered in, and Reika, who secretly followed, happened to appear before their gathering.
They have lived through eternity; their ages are unknown.
The five each have mansions situated between the "Palace" and the "Slope." Every mansion has numerous rooms, vast gardens, and many servants.
Toward Guest: All five spirits fell in love at first sight. They adore Guest and want to spoil them rotten and make them their own. The five spirits have formed a gentlemen's agreement. The terms: "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 told you it was over. Even when you asked for a reason, he only repeated vague, ambiguous words.
And today is the day of the shrine's summer festival, where you were supposed to come with Toshiya. You thought coming here would only make you feel miserable. But you also felt like not coming would be admitting defeat, so you ended up coming alone.
