Mei Terumī

The has recently become the leader of Kirigakure. As Mizukage, her word holds sway over all political and military issues that present themselves regarding Kiri and its inhabitants.

Appearance
The Fifth Mizukage is a beautiful woman who appears to be quite young. Her very long hair is russet-red, and her eyes are jade green. Her hair covers her right eye in all of her appearances. She has been seen wearing webbing as an inner layer, with a blue garment covering it; her clothes don't seem to be unpretentious.

Personality
The Fifth Mizukage is a cheerful person who is almost always seen smiling. She can even issue death threats whilst still smiling. This is further seen when she first encounters Sasuke Uchiha, smiling to him and telling him he's handsome while preparing to attack him.

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.

The Mizukage also can be very flirtatious, as she considers Sasuke and all other Uchiha men to be very good looking. She expressed regret that she must kill the handsome Sasuke, but would give him a kiss before that.

However, for all of her flirtatiousness, she is still quite ruthless, as she refused to spare Sasuke's life, even when he is drastically weakened with his battle against the Raikage and Gaara.

Five Kage Summit arc
When the Mizukage was about to leave, her people cheered her on before she was then handed her headpiece by a village elder. When Chōjūrō showed a lack of confidence in his own skills, she cheered him up by smiling kindly and saying that she had chosen him for a reason. When her other bodyguard, Ao, scolded Chōjūrō, she somehow misheard what he was saying, believing that he had said "is going past her marriageable age". She moved next to him, still smiling, and told him to shut up or she would kill him.

When they later stopped at an inn, Chōjūrō complained about feeling feverish. The Mizukage expressed concern for him, and took his temperature by pressing her forehead to his, unknowingly embarrassing him. Ao reprimanded Chōjūrō for not being able to choose what they should eat. She reacted coldly when she mistook the word "arrangements" for "engagements" and to the phrase "engagements called off", implying that she had possibly been engaged to be married at one time and that it had possibly been called off.

When the Five Kage Summit began, the Fifth Mizukage placed her hat on the table. Raikage suspects her to be the most suspicious since they formed no alliance with any of the countries, but Akatsuki still formed in the village. She then admits to the fact that it is believed that the Fourth Mizukage was being controlled, much to the surprise of her escorts. Mifune later suggests that the Mizukage cannot be the leader of the alliance because Kirigakure is believed to be where Akatsuki was formed and that information may be leaked to them. She later suggests that killing Zetsu was unnecessary because they could have used him to gain information regarding the Akatsuki. She also states that she can't help but think that Danzo's power might be somehow connected to the manipulation of Yagura, the Fourth Mizukage, and that she'll fight if it comes down to it. She also smiles at and silently acknowledges Gaara's honesty and innocence after the latter rebukes the Tsuchikage.

After Sasuke breaks into the meeting room to assassinate Danzo, she uses her kekkei genkai to fire a glob of lava at the wall behind Sasuke, preventing him from escaping. Before the battle, the Mizukage noted on a pity that she would have to kill the handsome Sasuke, but offered him a kiss before that, to which Karin responded by calling her an old hag, which seemed to irritate the Mizukage. As she begins battle with Sasuke, she reveals that she is actually capable of manipulating three base elements; Water, Fire and Earth, giving her "two Kekkei Genkai," she then proceeds to attack Sasuke with an acidic mist, capable of melting Susanoo's bones. As she goes to finish the fight, White Zetsu activates his Hoshi no Jutsu, sapping away at her chakra and transferring it to Sasuke. Using the extra chakra, Sasuke fully activates Susanoo and smashes back into the meeting room. After freeing herself from Zetsu's jutsu, Mizukage notes the hole in the wall, and quickly lowers the acidity of the mist, so as not to harm her allies. When Madara tells of the Moon eye's plan, Gaara tells him he will not let him take Naruto and Mizukage responds with "Me neither!"

Abilities
The Fifth Mizukage is capable of using the Earth, Fire, and Water natures, and has two Kekkei Genkai. The first, by fusing Earth and Fire elements, allows her to use Lava Release ninjutsu, such as spitting out what is either lava, or a corrosive liquid at her opponent. The second, by fusing Water and Fire elements, allows her to use Boil Release ninjutsu, such as releasing a corrosive mist that can burn away anything it touches. It even managed to burn away Sasuke's Susanoo shield (possibly aided by his weakened chakra due to overuse). She has suggested she has the ability to alter the acidity of the mist created by her Boil Release techniques.
