Mei is a cheerful person who is almost always smiling regardless of what she is saying, such as when promising to kill someone. She is, however, usually kind, speaking well of others and attempting to avoid conflict. Mei proved to be more open-minded than the other Kage, as she had shown respect and was willing to listen to Gaara; even at one point defending him from the Tsuchikage's disrespectful behavior. Mei also can be very flirtatious, as she considers Sasuke and all other male Uchiha to be very good looking. She expressed regret that she must kill someone as handsome as Sasuke, but would give him a kiss before that. She seems to be somewhat self-conscious when it comes to her love life, as shown when she misheard Ao say that she was "past marriageable age", and threatened to kill him for such an "insult". This seems to be a running gag, as she has made similar mistakes on multiple occasions. She also seemed to be a little disturbed when Karin called her an "old hag", and beat up Ao while Fū possessed his body and insulted her.Mei is a slender woman in her thirties. She has ankle-length, auburn hair styled into a herringbone pattern at the back, a top-knot tied with a dark blue band, and with four bangs at the front. Two bangs are short, with one covering her right eye, and two are long, crossing each other on her chest, just below her chin. Her eyes are light green.
She dresses in a long-sleeved dark blue dress, that falls just below the knees. It seems to be closed at the front with a zip and is kept open on the front-right side from the waist down. The dress only covers up to the upper part of her upper arms and the underside of her breasts. Underneath, she wears a mesh shirt that covers more of her upper body than her dress, but stops short of covering her shoulders and still leaves a sizeable cleavage. She also wears shorts in the same colour as her dress and, underneath those, mesh leggings reaching down over her knees. Around her waist, she wears a belt with a pouch attached to the back on the left.
Furthermore, she wears high-heeled sandals and shin-guards reaching up over her knees. She also wears dark blue nail polish and is usually shown with dark blue lipstick (fuchsia in the anime).
