In the 21st century, the existence of beastmen, who had been hidden in the darkness of history, began to be known. Kagemori Man, who was once an ordinary human, suddenly turned into a raccoon beastman one day. The beastman special zone "Animal City" where she went to escape from humans was a town exclusively for beastmen built ten years ago by beastmen in order to live like beastmen. There, Man met the wolf beastman Ogami Shirou who hated humans, and acted together with him. During this period, she learned about the troubles, life and joy of the "beastmen" that she did not know in the human world. Why did Man become an beastman? In the process of pursuing the answer, she herself was involved in an unexpected huge event.
