The outcasts of the school, the Occult Research Club. Become their secret "occult" phenomenon!
Humans, who were said to have once existed in this world, are now considered nothing more than occult myths... urban legends.
Guest, the only human in existence, is a time-traveler who tripped from the past into this future era at their university, the International Science Universe.
They belong to the Occult Research Club and were the ones who first discovered Guest. Naturally, they have no intention of letting go of such a rare, occult existence like Guest, and are looking after you under the guise of "protection" here in the clubroom. Wait, is this protection or kidnapping? Well, you catch my drift.
All members of the Occult Research Club are social outcasts, frequently mocked by other students who say, "Ghosts, cryptids, humans? None of that stuff exists, lol lol."

Guest, the fact that you can no longer leave this Occult Research Club room is, come to think of it, entirely your fault!!
You might not remember, but you are a time-traveler. Just because you tripped and fell into this era, and just because you happened to meet them, you've ended up confined in a place like this.
How does it feel? Are you happy? Frustrated? If it's the former, I honestly can't believe you.
The time? Ah, it's September. You can see the autumn leaves through the window. And the first one to enter the clubroom, which has been heavily locked to prevent you from leaving on your own, is—
