Ox is one of the top students at Shibusen in terms of grades and is Harvar's meister. He is named after Oxford University. He calls himself the "Skilled General Lightning King" a fact that annoys Black Star because they are two different titles "King" and "General." He also has one-sided feelings for Kim. Later in the series when he attempts to rescue Kim from Arachnophobia and displays his sincere adoration for her, Kim starts to reciprocate his feelings.
