History
10 years ago, he and the Queen met in the human world at the park of his hometown, known as a Connection between his world and her world. She claimed to be a runaway as well as a princess of her country. Naoya believed every bit of her story, as well as noticing the sadness behind her smile, and did what any kind person would do, he cheered her up. Later that night, the Queen had sexual intercourse with Naoya while he slept to regain enough magic to go home, [the only possibility]. As a result, Asuha was brought into the world. Three years later, the Queen brought Asuha to him and left her with him before returning home immediatly after, much to his chargin.

Asuha
She is the daughter of Naoya and closely resembles him. She arrives shortly after Naoya is officially hired by the princess and quickly becomes close to the princess and has a lively and free-spirited young girl around the same age as Lotte and Kimi. She comes to live at Lotte's and helps her to overcome the barriers that Lotte has had making friends at school. While energetic and seemingly uninhibited (she has the habit of going commando whenever she can get away with it, forcing her father to carry a pair of her underwear with him at all times) she can also show a maturity beyond her years when helping others out.

It is later revealed that her mother whose identity has always been a mystery her and Naoya both, is in fact Queen Mercelida, the queen of the monster realm and Lotte's mother, making her and Lotte half-sisters. This fact is known only to a very few and is kept very secret. Upon reuniting with the queen Naoya was able to thank her for giving him Asuha and said that his daughter was his reason to continue living after she abandoned him.

Lotte
He is the sole member of her harem with the title of "toy", and becomes her love interest. At first she pushed him away because of her hatred of men, but little by little she opens up to him, and starts showing jealousy when he gives other people attention like Kimi. Initially Naoya seems to take on a parent/guardian role, taking care of her in a manner similar to his daughter, however as their relationship progresses it is shown he has developed feelings for her, but then tells her he couldn't have sexual intercourses with her because he gave his heart to Kimi. Lotte states that she didn't want to do it anyway afterwards.
