Ryūzetsu

was a kunoichi that appears in Naruto 5: Blood Prison. Ryūzetsu was a childhood friend of Mui's son, Muku. Just like Maroi, she also had an undercover mission in order to investigate Mui as to the disappearance of Muku when he was still young.

Personality
Ryūzetsu was mildly serious as she was not amused by many things, such as Naruto's antics. She was also very strong willed and quick witted. She has shown to have some form of feelings for her childhood friend, Muku, as shown when she did whatever she could to stop him when he went on a rampage. She was not scared at putting her life on the line or dying for friends, as seen when she not only jumped in front of Naruto, and was impaled by Muku, but as she also gave her own life to save Naruto's, even though she was badly injured.

Appearance
Ryūzetsu had long white hair that flows to her waist that is covered by a green bandana which belonged to Muku and blue eyes with multiple circular patters much like Kurenai Yūhi. She wore a sleeveless kimono over a green top that only has a long green sleeve covering her left arm along with the green bandana. Both her arms were bandaged up to her elbows. She also wore black trousers with shinobi sandals.

Abilities
Ryūzetsu can create fire-like apparitions. She can also use a technique to heal or restore life in exchange for her own.
