Mabui

The Current Raikage's assistant is presumably a kunoichi from Kumogakure who is seemingly quite young and rather pretty. She's a dark-skinned girl who is seen wearing a very formal attire during work hours, also wearing long appropriate earrings and properly pulling her hair back into a bun except for the frontal part of it, which consists of two flat side bangs, a little like Haku, but much shorter. She appears to remain calm in the most frantic of situations, as shown when she, unlike her employer, the Raikage, took the news of Killer Bee's kidnapping and Jay's capture without any strong reactions. She's also shown taking Raikage's orders without any form of questioning, immediately busying herself with any tasks handed to her by him and seeking his guidance during desperate situations, much like Shizune with the Hokage, Tsunade.

Furthermore, she, like Darui, appears to be quite annoyed everytime the Raikage bursts through walls whenever the use of doors is required, and even suggests that he's broken through his office windows in more than one occasion.
