Ryūzetsu

Ryūzetsu had fair skin, waist-length white hair that is covered by a green bandana that has a long curved white stripe which had belonged to Muku and grey eyes with multiple circular patterns much like Pain's Rinnegan. 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. Overall, she disguised herself as a man in order to infiltrate the Hōzuki Castle, and nobody knew of her gender until she took off her kimono to dry off in front of Naruto.

Ryūzetsu belonged to the Grass Flower Group of Kusagakure and was childhood friends with Mui's son, Muku. As children, they both dreamt of resurrecting the glory of Kusagakure. Eventually, she witnessed Mui sacrificing Muku in a failed attempt to open the Box of Ultimate Bliss, leaving only his green scarf. She was seen wearing this same scarf as a bandanna during her trek into Mui's Hōzuki Castle in order to not only stop him from re-opening the Box of Ultimate Bliss, but to avenge Muku's death.
