Chōjūrō

Chōjūrō is the last of Kirigakure's Seven Ninja Swordsmen of the Mist. He later becomes the Sixth Mizukage, Rokudaime Mizukage, Literally meaning: Sixth Water Shadow). In the anime, shortly after the Fourth Mizukage's passing and Mei Terumī was made the Fifth, Chōjūrō was present when the village received an invitation from Konohagakure and Sunagakure to join an impromptu Chūnin Exams they would be hosting together. Ao noted that the village was still recovering from the Fourth's passing, so it was decided the Kiri-nin would not take part in this event. Despite his membership in the elite Seven Swordsmen group, Chōjūrō is a shy individual and seems to lack confidence in his abilities. He also greatly respects and admires the Fifth Mizukage, as he commented inwardly on wanting to protect her "beautiful smile".

By the time of the Fourth Shinobi World War, Mei has noted that he has become a lot more confident in himself as seen when he cut down Black Zetsu without reservation and then declares to the Fifth that as a member of the Seven Ninja Swordsmen of the Mist, he would guard the area with his life. Years later after becoming the Sixth Mizukage, Chōjūrō has seemed to grow well into his new role, appearing much calmer and confident in his abilities. Chōjūrō has short, tufty blue hair, and dark eyes. He also has pointed, shark-like teeth; a common trait of the members of the Seven Ninja Swordsmen of the Mist as well as apprentices share. He wears square, black-rimmed glasses connected to ear protectors, a blue pin-striped shirt and camouflage pattern pants. He wears his forehead protector on the front of his holster which he uses to carry Hiramekarei. The sword itself is wrapped in bandages leaving only the double hilt visible. He also has shuriken holsters strapped onto each of his legs. During the Fourth Shinobi World War, he still wears the same outfit but changed his forehead protector to that of the Alliance's. Years after the Fourth Shinobi World War, Chōjūrō grew noticeably taller and developed a firmer jawline with some chin stubble. He started wearing glasses with thicker frames and the ear-protectors he wore changed design. He retained his overall attire, but the straps of his sword-holster now only covers his left shoulder. Chōjūrō now also wears his light-grey pants without the dual shuriken holsters. Despite his meek demeanour, Chōjūrō is a highly capable ninja, earning acceptance into the Seven Ninja Swordsmen of the Mist, and being chosen as one of the Fifth Mizukage's bodyguards during the Kage Summit. During the Fourth Shinobi World War, he proved able to defeat Black Zetsu while fighting alongside his allies. Years later, Chōjūrō's abilities improved immensely as he was promoted to the rank of Sixth Mizukage.

Suigetsu Hōzuki has also referred to Chōjūrō as a master swordsman, even amongst the other Seven Ninja Swordsmen. As a kenjutsu practitioner, Chōjūrō wields a dual-handled sword called Hiramekarei, that is linked together at the handles by a chain. When released from its bandages, it releases chakra that can be shaped into weapons. He has been shown capable of creating an enormous hammer, and a massive longsword in an instant after storing a large amount of chakra in the blade. By the time he was Mizukage, he could create a copy of Hiramekarei with chakra for dual wielding, as well as create several knives strong enough to immobilise opponents. Chōjūrō is shown strong enough to wield Hiramekarei in its hammer form and send Sasuke, who was shielded by Susanoo, flying some distance away. In the anime, he could cut through thick wood with ease and attack with rotating movements, hitting every enemy around him. When he was Mizukage, Chōjūrō's kenjutsu skills had improved the point where he was on par even with Kinshiki Ōtsutsuki. Chōjūrō, now the Sixth Mizukage of his village, arrives at Konohagakure for the new Kage Summit with his bodyguard Misuno and comments that the Hokage is late for the Summit held at his own village. During another such meeting, Sasuke came forth to reveal evidence of a new White Zetsu Army being formed and a potential threat even greater than Kaguya. Ultimately, it was agreed to keep this information a secret from the public and allow Sasuke to continue his research and further investigate his sources. Chōjūrō attended the Chūnin Exams and sat with the other Kage during the third round. After Naruto is kidnapped by Momoshiki Ōtsutsuki and Kinshiki Ōtsutsuki, Chōjūrō, the other Kage, Sasuke and Boruto decided to rescue him. After being transported to the dimension where Naruto was, Sasuke battled Momoshiki while he and the other Kage fight Kinshiki off. During the battle, he restrained Kinshiki from moving after Sasuke destroyed his weapon, allowing Kurotsuchi to capture him. However, he later manages to break free and let himself get absorbed by Momoshiki. Momoshiki then later proceeded to capture Chōjūrō and the other Kage in his shadow jutsu before Boruto threw his Vanishing Rasengan to free them. With Sasuke's help, Boruto managed to defeat Momoshiki with a giant Rasengan. After Momoshiki's defeat, Chōjūrō posed for a photograph with the other Kage, Sasuke and Boruto.
