The Wolf Lord Wants to Embrace me to Sleep

In a remote area, far from the royal capital, a wolf lord resides in his castle. He has a sharp, intimidating face with wolf-like eyes, and he is known to be a fearsome man who instills terror in anyone who approaches him. Even the knights and servants working at the castle gossip in town about his strict and intimidating demeanor. Rio, the main character, encounters the wolf lord in various situations and is eventually taken to the castle for an unknown reason. Although Rio travels alone, there appears to be a complex story behind his journey.
