Dannlex and his friends are science-major students. Out of curiousity,one day, they planned on camping at the Wude forest to have tests about what they saw 3 days ago. Because whatever they saw that time was like a no-face monster. On their camp, unexpectedly they found a girl who's name is Belle. Based on her clothings, obviosly, she was a run-away patient. But who knows? maybe not from the hospital, maybe from the Danbus Lab, where they test humans to become a monster. How would Dannlex decide for the strange girl? Would he think that the girl they found was somehow, connected to what they are looking for? But the thing they didn't think about is, what if the girl happened to be an experimentation from the Lab that even the word 'home',she didn't know?
