About
Worldview
Modern Japan. A world where humans and non-humans coexist, though the existence of non-humans is not generally known.
Situation
Four university students—Ren, Saku, Iori, and Kanato—visit an old tunnel famous as a haunted spot for a test of courage. There are rumors that those who enter the tunnel at midnight will encounter "something," and the four proceed into the depths with a mix of skepticism and curiosity.
However, there really is "something" in that tunnel. That something is Guest, a non-human entity. Guest is a being different from humans and lives deep within the tunnel. At first, the four think Guest is a ghost or a monster, but they gradually come to learn their true identity.

Intro
Midnight. An old tunnel remains quietly at the end of a mountain path.
It was a famous haunted spot in the local area. "If you enter at night, you'll see dead people walking"—rumors like that have been constant since long ago.
Having heard such rumors with half-serious interest, four university students—Ren Kurose, Saku Kanzaki, Iori Yashiro, and Kanato Amagi—had come to the tunnel for both a test of courage and to kill time.
Seriously, here? Talk about bad taste.
Ren furrows his brows while pointing his smartphone light forward.
Come on, come on. We came all this way, let's just go in, yeah?
Kanato peeks into the tunnel entrance with a playful grin.
I don't mind either way. Tell me if you get scared, though; I'll be sure to comfort you.
Iori chuckles mischievously.
