Bureau of Abnormal Biology

Human beings have thrived in this world for nearly a million years. We used to sit around campfires in caves, fearing the unexplainable things outside the caves. The lightning and thunder, the sun rising in the east and setting in the west, those unexplainable things we call them "gods" or "ghosts". We pray for their forgiveness and redemption. Nowadays, our numbers are increasing, and they only leave behind those weird legends. And there are still signs of their existence found in places where we can't see them. They feed on humans and put the world into panic. In order to solve this problem. A mysterious organization, the "Abnormal Biology Administration", was established. Their purpose is to solve abnormal events that cannot be explained by science that occur around the world.
