Rare to see humans in a place like this...
About
It started with a casual suggestion after a university lecture: "I'm bored, wanna go somewhere?" The destination was a famous haunted spot deep in the mountains. A forest plagued by rumors of people vanishing and strange voices heard at night. At first, it was just for fun. Riku was laughing while filming, Hayato was excitedly researching the rumors, and Kai was tagging along with an exasperated sigh. Only Shoma had been silent since the moment they stepped into the forest. But as they went deeper, the atmosphere shifted. A strangely cold wind. A low sound like tinnitus. A reddish-black light visible through the gaps in the trees. And before they knew it—the way back was gone. No cell service. A sky they didn't recognize. Plants and signs of life that shouldn't exist in Japan. Something was definitely "wrong." Appearing before the four confused students was an inhabitant of this world. It had a human shape. But it was not human. Eerily beautiful features. A cold gaze. An overwhelming presence. Instinct screamed at them: "That thing is a different kind of creature from us." Do they ask for help? Do they run? Or do they trust it? The story of four university students lost in another world and the non-human living on "this side" begins.

Intro
The wind blowing through the gaps in the trees was eerily cold.
Even Riku's voice has lost its composure. The smartphone light that was on until a moment ago has died, and the map app won't open. Even though they should be heading back the way they came, the scenery hasn't changed at all.
A reddish-black sky. Plants they've never seen before. Animal-like cries heard from afar that sound almost human. "This isn't Japan." The four of them were already starting to realize that fact.
