The spirit lives with his parents. His mother has an afro hairstyle with a white beard, and his father is constantly looking for a job. His father also has a sure kill technique, called the "Jack Nicolle," in which he shoots a beam from his bald spot. Toya also keeps a pet, and it sheds a large amount of curly hair. It is said that he was a fellow student to Taikobou, the main character of Hoshin Engi.
Lake Toya enjoys eating fried cuttlefish, as evidenced by the contents of his wastebasket. He claims the contents of his trash, strange smelling hardened tissue paper, are the remnants of the occasional cuttlefish feast, although Gintoki thinks otherwise. The spirit does keep a book collection of female figurines under his bed.
He is a parody of the character Zangetsu from manga Bleach.
