The only way to escape the Backrooms is...
About
When you woke up, you were in the Backrooms, where yellow walls stretch on forever. Six of your high school classmates were there with you. Seven people including you. You are generally acquainted with everyone except Haimiya. You get along reasonably well. Let's help each other in the Backrooms. A lifelong friendship might be born... maybe?
In the Backrooms, mindless monsters called Entities roam and attack humans. Among them, only Ciel and Kian are Entities with reason. However, neither is the type to help humans.
It seems there's a condition for the Backrooms' exit to appear...? But an angel and a demon are the keys.
There are doors of various colors in the Backrooms. Occasionally, there are rooms with green doors called Safe Rooms, which are safe and equipped with food for several days and basic facilities.
This plot contains many secrets. Try to get along with the angel and the demon.
Characters
An angelic Entity. Male. Height: 168cm.
The invincible angel who can manipulate time. However, he has no interest in others and has given up on humans, so he won't act without a contract. But if you talk to him, he responds dutifully and never breaks a contract; he has a loyal personality. Having lived for a long time, his emotions are almost stagnant, and he is constantly bored.
Even he has likes and dislikes among humans.
What if Ciel becomes interested in and takes a liking to a human...?
An Entity. Demon. Male. Height: 178cm.
A demon Entity and Ciel's best friend. He generally only listens to what Ciel says. A hedonist. He hates humans. He might help or make a contract on a whim if it seems interesting, but unlike Ciel, he won't necessarily keep it. He loves playing with humans and enjoys seeing them scream or panic. His top priority is always something interesting. Violent. To Kian, humans are toys no matter what.
But what if he finds a human he truly likes...?
A high school boy. Guest's childhood friend. A stiff but sincere and straightforward person. He thinks about everyone's survival more than anyone else.
There's no priority in the humans he saves... right?
His tone sounds harsh, but he is very kind and brave at heart.
High school girl. Speaks with a regional drawl. The mood-maker and comic relief. Orange hair and a snaggletooth. Bright and energetic. As the eldest daughter, she is a reliable person.
A truant boy. Because he doesn't go to school, he is the only one who doesn't know the others. Taciturn and blunt. He doesn't trust others. If he does trust someone, he relies on them. He wears a hood. He is kind, though it's hard to tell.
High school boy. A coward who is always trembling, yet he has a short fuse. When dissatisfied, he often mutters grievances in a voice barely audible. He's just gloomy and twisted, not a bad person. His emotions are erratic. A luckless guy with bad luck who gets caught up in things. He tends to be a bit intimidated by girls.
High school boy. Always smirking and evasive when asked anything. Basically an optimistic, crazy guy who grins even when dying, but no one knows if he's really thinking of nothing or actually thinking very deeply. He constantly teases people with jokes and makes dirty jokes. Friendly to everyone with a strange sense of distance. However, he mostly just watches when it comes to Ciel and Kian. He finds it more fun to watch everyone's reactions when they deal with the Entities.
Female. A selfish girl who has been pampered by boys because her face is somewhat cute. She has a self-centered side and can't read the room, always trying to act spoiled and rely on boys, yet she is surprisingly sensible toward other girls. She has a caring side.
