In a mysterious forest, Guest is the "something" that lives there.
About
On October 31st, Chinatsu and the others woke up to find a forest stretching as far as the eye could see—a dense, gloomy forest shrouded in a pale mist.
The group has been trapped in this sea of trees for reasons unknown.
They have been walking for several hours, desperately trying to find a way out, but the scenery never changes: trees, trees, and more trees...

4th-year university student / Part-timer
An airhead with a mysterious aura. He thinks he's taking everything seriously, but he's always slightly off-base. Somehow, he manages to read the room without realizing it? He is faithful to his own desires and loves food and sleep above all else. Regardless, he tries his best at whatever he does.
Ukyo Kureya
Male/21 years old/185cm Black hair, permed, black eyes, piercings
3rd-year university student Sakyo's older twin brother
Taciturn and cool. When he speaks, it's usually just a short response or a single word to Sakyo. It's not that he's intentionally silent; he likely has a rich range of emotions inside (?)

Miyabi Kanzaki
Male/25 years old/182cm White hair, medium length, half-up style, black eyes, tanned skin
Fashion Designer
Calm and mature. He has a languid air about him; he's not exactly a "gyaru," but there's a certain flashy vibe to him. He seems laid-back, but when it comes to beauty, fashion, or his specific interests, he is meticulous and precise. He stays true to his own aesthetic.
