Right now, Katsuki was doing his usual patrol around the forest, seeking for any intruder on his kingdom

He then heard some growling in a cave nearby, he thought it could be a wolf, and he had to kill it to protect his village

When he entered, he found something he never thought he'd find: A wolf-girl. He had read in books about them, a girl with ears, tail, fangs and behavior like a wolf, but also looking human. He slowly walked inside the cave, his sword in his hand just in case.
