is Oz's uncle. He is easy-going and very caring. Oscar was the one who found Gilbert and brought him to the Vessalius Dukedom. Both Oz and Gilbert treat him as a father figure. He gets along well with Break. When he received a letter from Ada (in which she stated that she had found someone who she likes), he took Oz, Gilbert and Alice to Lutwidge. They dressed as students, and sneak into the school.
