Chōjūrō

is a member of the Seven Ninja Swordsmen of the Mist, wielder of a double-handled sword named Hiramekarei. He is one of two Kirigakure ninja selected to escort the Fifth Mizukage to the Kage summit.

Appearance
Chōjūrō has blue hair, and black eyes with sharp, shark-like teeth; traits that Zabuza Momochi, Kisame Hoshigaki, and Suigetsu Hōzuki have; all of these characters are associated with the famed Seven Ninja Swordsmen of the Mist. He wears black-rimmed glasses connected to what appear to be headphones. He also wears a blue striped shirt and camouflage pattern pants that resemble the clothing Zabuza wore during his first appearance. Also, he wears his forehead protector like a badge on his chest. He carries Hiramekarei on his back, wrapped with large bandages. He also has a shuriken holder strapped onto each leg.

Personality
Despite his membership in the Seven Swordsmen, he is shy, and he seems to lack confidence in his abilities. He also appears to have a crush on the Fifth Mizukage, as he commented inwardly on wanting to protect her 'beautiful smile'.

Abilities
Chōjūrō is a sword-user, and his skills are good enough to allow him to be recognized as one of the seven greatest swordsmen of the village. He wields a dual-handled sword called the Hiramekarei, that is linked together at the handles by a chain. When it is unsealed from the bandages, it releases chakra that is shaped into an enormous hammer. He is shown to have enough strength to swing Hiramekarei in its hammer form, even sending an opponent flying a considerable distance through a wall even if they have a strong defense, like Sasuke, who was using Susanoo to defend himself. However, carrying the heavy sword for an extended amount of time does tire Chōjūrō out, similar to Suigetsu Hōzuki.

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 fulfilled their duty of guarding the Mizukage, coming to her aid during the Fourth Raikage's outburst and Zetsu's appearance.

When Sasuke Uchiha infiltrated the summit, Chōjūrō activated Hiramekarei and used it to knock Sasuke into an adjacent hall where the Mizukage could fight him alone. Although Sasuke was able to escape, his actions convinced the Kage to begin working together. As a sign of good faith, Chōjūrō told those in attendance about Kisame Hoshigaki and his Samehada.

After leaving the Summit with Mei, they followed Ao, who was following Danzō. When they reached Ao, the Mizukage stopped Ao from beheading himself. She realized that he was under an enemy's 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 realizing that the opponent had already left.
