He is a swordsman who uses a one-handed sword like a rapier. He wields the Blue Sword, one of the Yin-Yang Swords received from Durkali. He practices a calm swordsmanship that belies his age. Reflecting this, while young swordsmen usually receive the Fire attribute in the Five Elements Divine Art, he received the Water attribute.

He even lost to Judith, who is still an Expert. He is in a relationship with Judith.
