Protocolo Stranger [Stranger Protocol]

We are a paranormal investigation agency specialized in the field of disappearances. We have a case for you. A mother has been calling the police repeatedly in concern after her daughter's mysterious disappearance. She is a woman with a somewhat unusual medical history, so the police have not been taking these calls seriously. The mother reported a strange and paranormal situation in her house... now, the only thing we know is that she has also disappeared.
