Jūzō Biwa

was a jōnin from Kirigakure and a member of the Seven Ninja Swordsmen of the Mist.

Background
Jūzō joined the Seven Ninja Swordsmen of the Mist and came in possession of the Kubikiribōchō, which he used many times to dye the battlefields red with the blood of his enemies. This level of brutality made him famous in several parts of the shinobi world. At some point in time, Jūzō and his team-mates encountered a small three-man squad comprised of Might Guy, Genma Shiranui and Ebisu. Surprised that the young ninja knew who they were, Jūzō acknowledged his team's growing fame. Before things could proceed further, however, they were confronted by Might Duy, who activated his Eight Gates technique so his son and his team-mates could escape. It is unknown what happened to him, but at least four members of the Swordsmen escaped with their lives after this encounter. His sword was eventually succeeded by Zabuza Momochi.

Personality
Jūzō was internationally known for his inhumane brutality.

Appearance
Jūzō was a slender and tall shinobi — about the same height as the sword he wielded. He wore a black tight-fitting sleeveless shirt with two light thin stripes on his chest, a striped cloth belt and light pants along with black arm covers extending from his hands to his biceps. Jūzō also wore bandages around his neck and face which also covered his ears. Like all members of the seven Swordsmen, he also had shark like teeth. He had no eyebrows, creases under his eyes and a cross shaped scar on his right cheek. He also had a red grid-shaped marking covering his jaw.

Abilities
As one of the Seven Ninja Swordsmen of the Mist, Jūzō was one of the most powerful shinobi Kirigakure ever produced. Like all members of his team he had great battle prowess and was highly skilled in kenjutsu. Wielding the Kubikiribōchō, which can regenerate from the iron harvested from the victims' blood, Jūzō was strong enough to dye battlefields red with his foes blood and gained international infamy for it.
