Okay, Here's my Original Character and Tsunade's profile. If you don't like either/or, tell me and I can fix them. I'd just really like to be Tsunade (I can play for Shizune as well if you'd like)
Original character name; Fuuyutsuki
Age; 29-30 (almost as old as Tsunade...)
Gender; f
Level; between medium and high, depending upon her state. He has the two-tailed cat sealed inside of her.
Appearance;

She usually wears either a black and light blue kimono with a pruple obi and puts her hair up to hide her cat ears when traveling to other lands.
personality; dignified and elegant usually, but angers easily and is very good at elements of revenge. She's very close and protective of those she feels are friends and dislikes small children intensely.
History; Left the leaf village at the age of 15 to seek new things and experiences. She traveled the world for a while as an actress/courtisan. Leaving her with many connections, but more loose ends than anyone knows what to do with. She's very close with Tsunade and thinks of Kakashi as a little brother. She's also not-so-secretly in love with Anko.
She carries many scars from years of persecution for her ideals and harsh tongue, more so for those reasons than for her cat-like attributes. She has since come to bond with the cat demon Nineko who dwells within her, and learned to surpress her. There are rare occasions when Nineko is released and acts of her own accord, leaving Fuuyutsuki to accept the consequences.
Now, for Tsunade/ Shizune (unless someone else wants to play her)
Names; Tsunade, Shizune
Ages; They'd never tell...
Genders; F
Levels; Tsunade, high, Shizune, medium
Appearance;

Personality; you know what they're like; Tsunade; Hokage, dominant, calculating and a heavy risk taker with her own life but not the lives of others. Shizune; a bit mousy, secretive and secretarial. Very loyal.
MY history; They met in a tavern when Tsunade was through gambleing and sloshed. She still had cognative thought and foccus enough to speak clearly and earn Shizune's love. So shizune took her back to the crappy little place where she was staying and helped her until the "morning after" was over and Tsunade had fallen in love with her. They stuck together through thick and thin afterward and could only hold on to each other, as Shizune was shy and Tsunade felt she could trust no one else.
Well, that's the story and if you have objections, state them now or forever hold your peace.
