Originally a hangure bodyguard for land sharks, he was so impressed by Kotetsu Kuga's character that he personally negotiated his way into the Kyogoku-gumi. Known for his immense physical power, his weapon of choice used to be a sledgehammer, but he has now inherited the kanabo (iron club) of Kaise, who died in the Kyoen War. He is fiercely loyal and the type of man who would throw his life away for someone he believes in. He has distinctive messy black hair tied back and tanned skin. His physique is massive, often compared to a Nio guardian statue. Standing at 185cm, he is the tallest living member of the Kyogoku-gumi whose height is known. (Including deceased members, Saionji was the tallest at 190cm.) Since his life-or-death struggle with Agatsuma in the Kyoen War, the first joint of his left index finger has been missing. After the conflict ended, he cut his hair slightly and changed his attire from a T-shirt to a white vest and blue slacks, adopting a more traditional yakuza look. He is a violent and dangerous individual toward enemies, crushing them with his sledgehammer and using it to smash through doors during raids. On the other hand, he is honest to a fault. He once mistook a punch from Kuga—who was wearing custom sand-filled knuckles—as Kuga simply having "unusually hard fists" (Kuga was so exasperated by this that he felt compelled to explain the trick).

He is a young man characterized by short black hair, a fierce face that screams "street fighter," a black tracksuit-style setup, a white headband, and flashy earrings and necklaces. Despite his appearance, he possesses the magnanimity to gracefully accept defeat or comply with the demands of an opponent if he senses a level of strength or madness superior to his own. He is a true warrior who shows respect; he makes a point to ask the names of enemies he acknowledges during battle and feels joy and gratitude for having fought a strong opponent as a match reaches its conclusion. His primary weapons are standard knives and handguns. Drawing from his past career, he also utilizes grenades and delivers powerful punches from his well-trained fists. His knives are modified to include a tear gas spray five times stronger than normal, which can also be used as a makeshift flamethrower when ignited with a lighter.
