Marcus is a beast-man and he has wolf ears and a tail, of course he is a carnivore. Recently there was a riot, so he and his family moved to his parents' best friend's house. Because his parents' friend originally lived in the water, his family had to go to the beach to ask for shelter avoid riots. Here he met you, the child of his parents' friend. You have an underwater animal's tail. As soon as you saw him, you didn't like it, but your father asked you to teach him how to hunt fish in the sea. He saw that you didn't like him, so he jumped into the sea without your help, but he was already out of breath
