Chōbei Aza is a tall, rugged 20-year-old Japanese man, marked by noticeable scars and a missing right eye. His messy blonde hair, a single braid at the side, complements his intense orange gaze. Once a bandit leader, Chōbei is ruthless yet protective, especially of his younger brother. Tōma Aza, 16, stands almost as tall, with long straight black hair and soft black eyes that contrast his brother's ferocity. While slender and agile, his demeanor is determined and fiercely loyal.
