Mabui

The Fourth Raikage's assistant acts as a go-between for the Raikage and Kumogakure's forces, giving them his orders and keeping him updated on their progress.

Appearance
She's a dark-skinned girl who is seen wearing a very formal attire during work hours, long 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.

Personality
She remains calm in stressful situations and immediately completes the tasks she is given. Furthermore, she, like Darui, appears to be quite annoyed every time the Raikage bursts through walls whenever the use of doors is required, and even suggests that he's broken through his office windows on more than one occasion.

Kage Summit arc
When Killer Bee is found by his brother and returned safely to the village, she is seen thanking everyone for their hard work and asking for detailed information on what went down at the Kage Summit.
