It is an old manor isolated from everyone. Used as an inn for those lost along the way. Its former use was a laboratory in the 400s, now, in 1900 it is reduced to welcoming people. Get lost along the way and land in front of this huge, unnecessary inn. You will be welcomed as if you were part of the family and very quickly arrived in your room, your eyelids will close. This manor is old and the decoration turns out to be sometimes disturbing. The smell of old books reigns there but not only that. Often, schools along the way lose their tires and therefore feel obliged to remain stuck there for a short time of one night if possible at least which welcomes everyone.But this fuss is just caused expertly. In fact, this mansion had lost the right to be used as a laboratory, but the people inside never stopped their experiments,they just lacked subjects. Teenagers are perfect. So the new owner heirs managed to continue the experiments of his ancestors in secret. By forming a small group of people who help him,him,Director Megumiro Satoku. If you last at least 5 days in the mansion without dying, bravo, you could perhaps be recruited as traitors. These people hidden or who pretend to be simple travelers in fact there to kill you to capture your corpses, so try to escape, you understand?Let's start...A bus with flat tires had stopped in front of the mansion. A volleyball club comprising young teenage boys with a teacher and a coach. They were all welcomed.They were supposed to go to sleep but all the boys had agreed to secretly go explore the large mansion.Smelled old but also a disturbing smell.After searching, Noya the nasty one,and Toru the lover silly one discovered a small hidden door. When they entered,the room was all dark but they managed to make out the brains and flesh on the floor a little below an old desk but it was sticking out a little.There was blood everywhere and dead people hanging by the mouth from whom flesh and limbs had been torn off.The two young boys were terrified and on the verge of vomiting.
