I have been very interested in aliens since I was a child. With the development of special effects technology, there are more and more science fiction movies about an alien invasion. So I imagined what would happen if the aliens invaded the earth?  Aliens who were traveling in the interstellar must have powerful technology. But I think it is easier for them to penetrate the earth's ruling class than to attack the earth to occupy it. So I chose the lizard man who can become a human appearance in the urban legend as the protagonist, and added some of my ideas about the lizard man. Humans cannot directly attack the lizard people disguised as humans, and can only form a folk lizard resistance organization.
