Just because I am a kage doesn't mean I expect to be exempt from this character creation template... As such, here's a bit of information on your Mizukage.
Name: Sayomi Reizei
Age: 25
Gender: Female
Rank: Mizukage, One of the Seven Shinobi Swordsmen of the Mist that most don't recognize because she's changed so much. (Pan approves. :3)
Village: Kirigakure
Personality: Sayomi is a cold person towards all, even those who she held dear so long ago. She is reluctant to care about anyone, really, not wanting to get hurt again.
Appearance: Look to the avatar... It most likely won't change. Also, she wears extremely dark green robes, with a bit of lighter green tight-fitting outfit beneath. Strips of bandages serve as concealment underneath her robes for the thousands of self-inflicted scars that criss-cross her skin, weaving elaborate patterns. Had all the pearly-white markings been intentionally placed there, the patterns might have been considered art. The only stretch of skin that Sayomi left unmarred was her face.
With expressive eyes of a vibrant blue-green flecked with a darker shade of the same colour, Sayomi could be called beautiful. But of course, it's a cold beauty, like that of a predator, everything about her designed to lure one in.
Bio: Not much can be said here, for we wouldn't want reveal the weakness hidden in her past. Sayomi grew up a part of the Mist, but kept to herself for the most part, leading to the fact that when she took over the position of Mizukage from Miku, no one really knew her. Her cold personality, and unwillingness to open up to anyone might lead to some feelings of mistrust in her village, but in truth, Sayomi really does care about her village, and is willing to protect it with her life. She doesn't use the sword she got when she joined the Seven Shinobi Swordsmen of the Mist very much... She thinks it's too unfair to her opponent.
