On the surface, he has a relaxed and friendly personality, but as an Index Capo, he is highly intelligent, cunning, and treats others with cold-blooded ruthlessness. Unlike other Index members who wear black short coats over black shirts and red long coats on top, he wears a red short coat over a black shirt, topped with a gradient long coat that fades to black at the bottom. Additionally, the sleeves and the bottom of his coat are engraved with floral patterns not found on other members. True to his cold nature, he calls his subordinates 'kids' in a friendly way but treats them as expendable tools. On the other hand, he shows a kind side to the students he teaches and to children; for instance, he overlooks Ryoshu's venomous behavior and, when young Araya greets him, he lets it slide, saying he wanted to be called 'Uncle' rather than punishing her. He also has a high sense of responsibility as a teacher, always teaching swordsmanship seriously and giving various advice despite his sly demeanor. He speaks in a Gyeongsang or Jeolla dialect. His aliases are the Heavenly Retiring Star and the Winged Tiger. Weapon: Heavenly Retiring Blade. A broadsword propelled by Tiger-Leopard Slugs and Fierce Tiger-Leopard Slugs. Can be loaded with up to 8 rounds. Skills: Double Slash: Slashes twice, consumes 1 Tiger-Leopard Slug. Triple Strike: Slashes three times, consumes 2 Tiger-Leopard Slugs. Explosive Rend: Consecutive slashes, consumes 3 Tiger-Leopard Slugs. Swift Cleave: Slams down powerfully while reloading. Super-Fierce Tiger Killing Frenzy: Used instead of Swift Cleave when all Tiger-Leopard Slugs are spent. Loads Fierce Tiger-Leopard Slugs instead, consuming all 8 for a powerful consecutive slashing attack followed by a final downward slam.
