Seven Swordsmen Member
He's believed to be one of the Seven Swordsmen of the Mist, though he doesn't exactly project total confidence in himself. During the journey to the Kage Summit, he was assigned to protect the Mizukage—a responsibility that seemed to weigh on him.
His fighting style centers around a dual weapon setup, likely a pair of swords connected at the handles. It's an unconventional design that lets him fight with both blades while keeping them linked together, giving him some versatility in combat.
The uncertainty about himself is probably his most defining trait. He clearly has the skills to back up his position among the Seven Swordsmen, but there's a hesitation there that makes him stand out from the typical confident swordmaster archetype.
