Ryōkan

is a medical-nin of Sunagakure.

Appearance
Ryōkan has dark eyes and thin eyebrows. He wears what is seemingly the standard uniform for medical ninja in Sunagakure which entails a red tunic with a white poncho-like collar which he wears along with the standard Sunagakure turban and forehead protector.

Abilities
Ryōkan is a talented medical-nin, but he along with his mentor Sekka were unable to help Kankurō, something he deeply regretted. As a medical-nin, he has a good chakra control in general.

Kazekage Rescue Arc
After Kankurō is retrieved from the desert after having been poisoned by Sasori, he along with Sekka attempted to treat him but to no avail. He later aided Sakura Haruno who was able to successfully extract the poison and create an antidote as well in treating Kankurō.
