Mizuki Strikes Back Arc
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.

Mitate appears later trying to recover the Menma's memory, but did not succeed.
