Owen is an middle-aged man with short light-colored hair. He wears a pair of rimless glasses.
For the Royal Knights Selection Exam, Owen watches the matches as part of the team of high-rank healing mages. After the first match of the tournament, Owen assists in healing the members of Team B.
After the tenth match, Owen accompanies Julius Novachrono and Marx Francois to the battlefield and begins treating the heavily-injured Finral Roulacase. Before the next match, Owen moves Finral to a safer location and continues treatment.
Several days later, after Julius is fatally stabbed, Marx is sent to fetch the healer, but as they fly to the tower, they are possessed by elf spirits and attack Magic Knights along the way. When they threaten to harm Julius's body, Yami goes on the offensive and quickly knocks them unconscious.
- The elven tattoos on Owen's cheeks are Rods of Asclepius, a reference to his Healing Magic.
