Double World Deception

In 2025, things that humans cannot understand broke out in the world, such as "human-eating highways", "mysterious room 404 with no return", and so on. Incidents such as this began to occur all over the world. In order to deal with such incidents, humans established a special team "Patient Headquarters" to investigate such incidents. It was found that most incidents were caused by something incomprehensible. These things could be people or items. The patient headquarters named them "monsters" or "weird".
