Ryūsui has long chin length light-brown hair and light-coloured eyes. He wears a black bandana Amegakure forehead protector tied in the back and he has a black beard. He wears a long thick white scarf around his neck with one piece of the scarf hanging down the front to below his waist. He wears a black long sleeved shirt with a white belt around the black shirt. He also wears a pair of short black pants with bandages below on his legs. He also wears a pair of black shinobi sandals.
Ryūsui is highly loyal towards Pain and Amegakure, looking up to Pain with admiration due to him protecting the village and will swiftly admonish anyone insulting or even complaining about him. He is also a proud person, refusing to betray his comrades during interrogation, though this seems only to be on a superficial level, given that he squealed moments later due to fear of being forcefully transformed. Ryūsui also seems to harbour resentment towards outsiders who doesn't know anything about his home country.
Itachi Pursuit Arc
He and his partner, Yūdachi were captured by Jiraiya. When they refused to tell Jiraiya any information on Pain, even after tickle torture on his partner, he transformed Yūdachi into a frog, which frightened Ryūsui into divulging information about Pain. Jiraiya then tries to control Ryūsui in an attempt to find Pain, but is found by Konan. Ryūsui then follows Konan's orders to leave and is able to escape.
- The anime expands on his situation, seeing as he is captured by Jiraiya who learned about him from his wife, Tezuna.
- Ryūsui (流水) means "running water", or "stream".
- (To Jiraiya) "Go ahead, make me a frog or whatever! I'm not telling one more damned thing! Even us underlings have our pride, that of a shinobi… ! I don't have anything else to tell an outsider who doesn't know a thing about our country!"
