What is the definition of monster?
In the eyes of ordinary people, they are creatures whose existence has not been confirmed or denied by science, or abnormal people with abilities beyond ordinary people.
Or maybe it is something that has long been forgotten and submerged in the information technology society.
But in real life, there are really monster-like people in the eyes of ignorant people.
They were gathered in the same place for training until they could be submerged in the crowd and assimilate.
