Chōjūrō

is a shinobi from Kirigakure's Seven Ninja Swordsmen of the Mist who became the.

Personality
Despite his membership in the elite Seven Swordsmen group, he 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.

Appearance
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. Also, 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.

Abilities
Despite his meek demeanour, Chōjūrō is a capable ninja, whose skills made him a member of the Seven Ninja Swordsmen of the Mist — a group comprised of Kirigakure's strongest swordsmen. The fact that he was also chosen as one of the bodyguards for the Fifth Mizukage during the Kage Summit implies that he is quite powerful. Suigetsu Hōzuki has even referred to Chōjūrō as a master swordsmen, even amongst the other Seven Ninja Swordsmen.

Kenjutsu
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.

Chōjūrō is shown to be strong enough to wield Hiramekarei in its hammer form and is capable of sending an opponent flying a considerable distance even if they have a strong defence, like Susanoo.

In the anime, he is strong enough to cut through wood with ease and is seen attacking with rotating movements, hitting every enemy around him.

Five Kage Summit Arc
Chōjūrō and Ao were chosen to escort the Fifth Mizukage to the Kage Summit. During their trip to the Land of Iron, Chōjūrō was frequently embarrassed by the Mizukage's concern over him, which earned him scolding from Ao. Once they finally arrived and the meeting began, Ao and Chōjūrō rushed to her defence during the Fourth Raikage's outburst and later White Zetsu's appearance at the Summit.

When Sasuke Uchiha infiltrated the conference hall, Chōjūrō activated Hiramekarei and formed it into a hammer which he used to knock Sasuke into a sealed off, adjacent hall where the Mizukage could fight him alone. Although Sasuke was able to escape, his actions convinced the Kage to begin working together. When Tobi appeared and told the attendees of his Eye of the Moon Plan, Chōjūrō silently listened on and later after the masked man had left, as a sign of good faith, Chōjūrō told those in attendance about Kisame Hoshigaki and his Samehada but was cut off by Ōnoki who stated that they were already aware of this information.

After leaving the Summit with Mei, they followed Ao, who was tracking Danzō and his delegation. When they finally caught up with Ao, the Mizukage was able to stop Ao from seemingly beheading himself. She realised that he was under enemy control, and requested to use Hiramekarei to force him out. Fū insulted her upon learning that she knew he wasn't really Ao, and she quickly punched Ao before realising that the opponent had already released the technique. Later, when they return to Kirigakure they are informed that the daimyō had approved the formation of the Shinobi Alliance.

Adventures at Sea Arc
Chōjūrō was sent by the Mizukage in a diplomatic mission to better Kirigakure's relationship with Iwagakure, along with Kurotsuchi and Akatsuchi who were also sent by Tsuchikage on the same mission to stop Ganryū in the process.

Shinobi World War Arc
Chōjūrō attended the last meeting that was held by the Alliance in order to fully prepare for the upcoming war. The Mizukage told him to contact Ao in the Sensor Division and tell him that they needed to hurry. Chōjūrō later joined Mei in guarding the various daimyō during war. When Black Zetsu located the daimyō, he, Genma Shiranui, and Raidō Namiashi alongside the other members confronted the Akatsuki member.

As the battle between the two sides waged on throughout the night, one of Naruto Uzumaki's shadow clones arrived to help in the battle. During the fight one Black Zetsu's branches caught Naruto's foot, causing his Rasenshuriken attack to miss. Chōjūrō used that opportunity to attack from behind with his Hiramekarei. Forming it into a longsword, he cuts through Black Zetsu, and stated that the more confident he was, the stronger his strike. He then pinned Black Zetsu to the ground with the tip of his sword and told Mei — who was being called away — to deal with the reincarnated Madara Uchiha and that as one of the Seven Ninja Swordsmen of the Mist he would defend that point with his life.

Creation and Conception
Wanting to create a younger character, Masashi Kishimoto gave Chōjūrō short hair and attire that was not that of the standard shinobi. Then wanting to give him an air of unreliability, he immediately gave him glasses. The jagged teeth, Kishimoto admits, was simply an indulgence on his part.

Video Games
In Naruto Shippūden: Ultimate Ninja Storm Generations and Naruto Shippūden: Ultimate Ninja Storm 3, Chōjūrō is a support-only character.
