Leo is a young man with thick black hair, amber eyes and narrow framed glasses. He is only seen wearing the Jenis Academy uniform consisting of a blue and red blazer with gold decorative elements on the wide lapel, a white collared shirt and a green brooch with two red cords.
Leo is a rigid and pragmatic person, and a stickler to the campus rules. As a student, he's very observant, capable and dedicated, and because of this students mistake him as the real council president. He is also matter-of-fact about conversations, saying only what's necessary to get his point across.
Leo enrolled at the prestigious Jenis Royal Academy in Liberl, where he volunteered as the student council's secretary and accountant. Much of his time in the student council was trying to find the council's president, Lechter Arundel, who would avoid meetings and his responsibilities.
