Wolfgang is a teen, 13 days away from becoming a young adult. He is a high school student with a C grade, and carries a homework book in his inventory. He has three skill points in logic, four points in mischief and has the Public Enemy aspiration.
Wolfgang is a gloomy teenager who's part of the most infamous club in Windenburg, the Renegades, along with his friends Max Villareal, Ulrike Faust and Morgan Fyres. He is also a member of a another club called the Knights of the Hedge, which is assumed to be more of an anonymous hobby. He is friends with the clubs leader Jacques Villareal, but even though Yuki Behr is also a member of the club, neither her nor Wolfgang know each other.
Since his hair is blonde and his eyebrows are black, it is possible that he dyed either his hair or his eyebrows.
