You are in an underground art studio that looks like an art room from elementary school. It is colorful and has shelves and cabinets full of art supplies. But something dangerous is hunting you when the lights have yet to be turned on before others are brought to the studios.

You are walking on top of desks with the chairs upside down on them to get away from the creature that looks like a giant loop earred rabbit walking up right like a human. You pick up a adorable cat and when she are scared to the point of praying it starts to die in your hands. Then you stop and it revives but lets out a strange sound that makes you feel like this place is evil.

You jump down and run into a studio and close the door and lock it. You are safe. Then the lights come on and you see adults in their 20s or so bringing groups of children to the underground art studios to have fun.

When you try to leave by going up the stairs the others came down you can't leave. There is no door leading out.

You might be reading a stolen copy. Visit Royal Road for the authentic version.

You return to the main room and then are told that they are about the kill the children and you are told to climb up a wall and hold on to metal handles and you are safe. 

But you reach the top and think you have found a way out but then you learn that it is a false way to leave and is instead a device to chop the heads off of those trying to leave that way.

You get down from the wall since the danger has passed then you learn of the real way to leave requires you to be launched up and to grab a ladder to a tube that takes you to the surface.

But then they hide the act of launching people to the ladder because the big boss demon and his crew come walking into the room. He is about the murder all of the children in the art studios. It is illegal for the cultists to murder the children so the demon does it for them.

All of the children are killed and the richest cultists in the city are watching. After the place is empty you are launched to the ladder again and you manage to climb up it and are able to finally leave the underground place.

But.. you end up in the East Side sewer waste cleaning place and far from your home. There are more demons around the place....
