Anime Version

A traveling doctor from a guild known as the Way of the Five Grains (五斗米道, Gotomedō) (a title Kata insists must be voiced out as loudly and enthusiastically as possible each time it is mentioned). He is on a quest to search for and seal away a cursed magic book known as the Crucial Keys to the Way of Peace. He first appears in Shin Koihime Musō when Kan'u's group comes across him along their way and he treats Chōhi's stomach ailment. His quest takes him to Sōsō, who herself was seeking the book to find a treatment for an ailment that her own physicians could not cure. But when Kata offers to treat it for her, his way of explaining the treatment causes a misunderstanding that gives Sōsō the impression that he is a pervert, and he is chased out in anger by Sōsō. He returns at the season finale where he helps the Kan'u and Sōsō forces defeat the Yellow Turban rebels without fighting them.

He returns in the third season, helping General Kanshin trying to find a way to end the curse cast upon her.

He does not mind offering medical aid to those in need, and is rather enthusiastic about it, yelling like a super robot hero and performing cool-looking poses all the while.
