Mei Terumī

The is suggested to have only 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. She is a young, beautiful woman and one of two known female Kage (the other being Tsunade).

Personality
The Fifth Mizukage is a cheerful person who is almost always seen smiling. She even can issue death threats, but still with a smile. She also seems to be somewhat self-conscious when it comes to her love life, as seen when she misheard one of her subordinates that she "past marriageable age", she threatened to kill him for such an "insult". This seems to be a running gag as she has in the most recent chapter mistaken Ao for saying "engagements" when he said "arrangements" and "Call you ambitious" for "Called off" leading to yet another death threat.

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

When they later stop at an inn, Chōjūrō complains about feeling feverish. The Mizukage expresses concern for him and takes his temperature by pressing her forehead to his, unknowingly embarassing him. Ao scolds Chōjūrō for not being able to choose what they should eat. She reacts coldly when she mistakes the word arrangements for "engagements" and to the phrase "engagements called off", implying she possibly was engaged to be married at one time and it was possibly called off.
