Ugai

is a medical-nin of Konohagakure.

Sasuke Retrieval Arc
He is an inexperienced, yet knowledgeable, medical-nin. He helped Might Guy find Tsunade in the Konoha Hospital. He then looks on in shock when Migaki arrives suddenly, telling Tsunade that something terrible had happen.

Appearance
The manga depicts him as a young man with dark-coloured hair wearing the standard uniform of the hospital medical ninja. In the anime, however, he is given a much older appearance with a beard and glasses.
