On a planet, everyone has beasts, some are carnivores, some are herbivores. Beasts will appear when they are 16 years old. At this time, the beasts will do some things related to the habits of their beasts, such as cat beasts, because they have not adapted to it. People will especially love to eat fish. At the age of 17, after a year, the orcs will control their animal nature. This time I will tell a short story about a black cat boy who cannot control his animal nature and his new neighbor Mr. White Cat ovo
