By main characters, I think you mean the player characters. If so, yes, they have names. The boy is named Hilbert, and the girl is named Hilda. Their Japanese names are similar as well. The boy's is Touya, and the girl's is Touko.
The main characters in the book The Door In The Wall the main characters are Robin, a boy who lost feeling in his legs, then wants crutches, John- go-in-the-wynd, the boy who delivered the letter to Robin from his dad, and Brother Luke who helps take care of Robin.
