BFB SACRIFICE SANCTUARY

All the BFB contestants woke up in a dark room and a person with a black cloak approached them and announced some things they need to know. 1 by 1 they keep disappearing every day and some of the contestant worry about them. They need to find a way out. But some people will sabotage their plans
