Ryuuzetsu

Ryuzetsu met Naruto in the Hozuki castle as a fellow prisoner. He warned him to not get himself into more trouble than he already is in. Naruto attempted his second escape by jumping off the cliff and into the ocean.

Ryuzetsu went behind him and warned him not to but Naruto ignored him and went anyway. She also went after him and jumped in to save him. After taking shelter, she told Naruto her mission and they formed an alliance to take down Mui and the Box of Ultimate Bliss.

When she tried to assassinate Mui while he was sleeping it turned out to be Maroi in disguise and this incident made them form another alliance. During the prison riot, Ryuzetsu took advantage of this situation to attack Mui but it turned out to be Kazan in disguise. By that time the real Mui brought the Box to the prison yard and used Naruto’s chakra to open it. Ryuzetsu was surprised to hear that Mui's wish was to see his son again instead of resurrecting Kusagakureand was shocked to see Muku come out of the box being corrupted by Satori and impaled his father.

During Satori's rampage, Ryuzetsu kept reasoning with Muku about Satori's ability of sensing fear and killing being ineffective against her due to her lack of either. When Satori attacked Naruto, Ryuzetsu jumped in front to block it and she and Naruto got impaled. Naruto defeated Satori and Muku with Wind Release: Rashenshuriken and Mui's help.

As Muku and Satori were dying, Ryuzetsu remembered her old times with Muku and cried. When Sakura was unable to heal Naruto’s stab wound, Ryuzetsu stepped in and used her Dragon Life Reincarnation to save Naruto’s life while sacrificing her own. As she lives her last moments, she kisses Naruto and entrusted him to continue on with her will. She and Mui were buried outside the Hozuki castle and Muku's Bandana is tied around her gravestone.

After her childhood friend's death, Ryuzetsu became a stoic kunoichi who was really fascinated by anything. She is quick witted and very strong willed. She has a deep sense of morality and loyalty and never hesitates to put her life on line for her comrades.

Ryuzetsu had fair skin with waist-length white hair which was covered by a green bandana given to her by Muku. She also has grey eyes with circular patterns like Pain. She wore a sleeveless kimono over a green top that only had one long sleeve covering her left arm. Both her elbows got bandages too and she also wore black trousers with sandals.

Ryuzetsu is skilled at infiltrating and she also has a very powerful life force, which was why she was able to survive even after being impaled. She can use Fire Release and can create Fire-like apparitions to attack her enemies.

She uses Fire Release: Heavenly Prison which proves that she had strong chakra. She is also able to use her clan's kekkei genkai which helps to heal or restore life in exchange for her own life.
