Yun wrote the book on Relentless Combat Techniques. No, seriously. That's the title. Yun's amazing reflexes and two-weapon technique give him an edge over any monster, but it's his endurance that truly sets him apart. When anyone else would ask for a breather, Yun keeps going. In fact, Yun petitioned the Guilds to let him attempt a solo recapture of Arcadia. Alas, while Yun's 'filibuster combat style' is truly stunning, even he needs assistance sometimes. He just hopes that the others can keep up.
