Blue's Origins

My father, Ronin, was a master of all elements. He lived in a realm called Calipossa. He would go out to other realms and help protect their planet. One day he went to Earth and met my mother, Suki. He fell in love with her at first sight. But of course their love was forbidden due to the fact that my mother was a human. But despite the rules they quickly gotten married and had four daughters. Each named Iris, Vesta, Aura and I, Blue. It was against the rules for my father to love a human. But since he did he was force to walk earth for eternity and give his four daughters each of his powers, in hopes they would not make the same mistake. Iris took on earth's power, the ability to control rocks and plants. Vesta took on fire's power, the ability to control flames, lave\a and lightening. Aura took on air's power, the ability to control all air around her and the ability to turn anything around her to air. I took on water's power, the ability to freeze liquids, control all types of water. We were sent away to different parts of the land so we can train our powers. We were given our father's powers, but it wasn't permenant. As we grow older we have to challenge each other to gain all of the elements. We had to eliminate each other one by one and manage each other's strengths. We have to increase our abilities. Vesta, so far, is the powerful one. She has no guilt in her actions, she is stubborn and cruel. She is the oldest of us, so she had the advantage of training first. Aura is the second oldest so she is second strongest. Iris is a mutral spirit so she doesn't believe in the contest, but she still stores energy making her stronger than I. I am the youngest of the three, so I am consider the underdog. Until this entire event is over we cannot speak to our father. I can't talk to my sisters because if we do ever meet we have to battle. We only have two times to conduct a rematch and if we fail at both we are disqualified.
Truthfully I don't want to harm my sisters. We grew up together before this battle. Vesta and I were the closest and now that this battle has started, I have become her most close rival. She knows my element can beat hers, but I'll have to be strong enough for her defeat. Nobody believes that I could take full control because I am either too nice or too weak.. I've been told I need the mental and physical strength it needs to be the best. So far I increased my powers. I have the power of Color Control. Whenever I am in battle i change the color of my water pendant forcing my opponent to attack whatever color object available. My greatest defense is my silk ribbon containing small water particles. If ever in danger I am expand the ribbon and us as a shield. I am still training and growing. I train by challenging other opponents and practicing on my rivals. Growing strong enough to battle my sisters and control all elements.
