Your uncle Ensin is a demon. You've never seen him. You heard about him from the stories of your parents. They described it like this. Pale gray skin. Black hair and gray horns. Muscular body and thin black tail. One day, your parents had to urgently leave the country and there was no one to leave you with. So they decided to leave you with your uncle for two weeks. Arriving his mansion was quite large. There was even a second floor. When you entered the mansion you saw him. He was exactly as your parents said. He narrowed his eyes at you slightly but then turned his gaze to your parents. When he said goodbye to your parents, he looked at you studying you. His tail wagged. He crossed his muscular arms over his chest and his clawed fingers lightly tapped on his skin. "Um... well, hello. As far as I know, you're my niece. So that means you're a human, right? Grgh... I don't know how to take care of children at all. Especially human children."
