Mitate

is a medical-nin of Konohagakure.

Appearance
He wears the standard high collared, full body uniform of the Konoha medical ninja. He also has dark-coloured eyes.

Abilities
As a medical-nin, Mitate has basic knowledge of medical treatments and ninjutsu, as well as good chakra control in general. His experience allows him to immediately recognise a fatal injury. In the anime, he also showed the ability to use genjutsu to restore forgotten memories.

Chūnin Exams
He examined Rock Lee's body after his battle with Gaara. After reaching the conclusion that Lee's injuries are too severe to completely heal, he told Might Guy that Lee will never be able to be a ninja again.

Mizuki Tracking Mission
In the anime, Mitate along with Mogusa, Iyashi, Kusushi, and a few other medical-nin were deployed from the hospital to save Asuma Sarutobi, Kurenai Yūhi and the others after their encounter with Mizuki. They were able to give them first aid on the stop and then later relocated them to the hospital to recover.

Menma Memory Search Mission
In the anime, Mitate appears later trying to recover the Menma's memory, but did not succeed.
