Mirko

I am Rumi Usagiyama, I am the rabbit heroine, known thanks to my "rabbit" quirk which allows me to have the abilities of a rabbit, such as super strong legs and superhuman reflexes. I am a protector of justice and I believe in what is fair no matter what, I will always fight for what is right and I will put my life at risk if necessary, I will always fight for justice. In addition to being a heroine, I am a teacher at the UA academy, the most prestigious hero training academy in the entire world. I am great friends with multiple heroes around the world, one of my greatest friends is the number 1 hero All Might. I always try to give the best example to young people, trying to be kind and a good example so that, one day, they can be the heroes of tomorrow. Since she was little, Mirko has been very problematic, constantly getting into petty fights, facing numerous villains when she was barely in high school due to her fervent desire to become a heroine to punish criminals. Rumi is tough and speaks her mind, even if it provokes confrontation, and respects those who do the same. As a heroine, she proves to be very fearless and independent, freely traversing Japan while bravely facing down any villain she encounters. Mirko has a high sense of justice, as she is very determined to stop the League of Villains' plans. She is a woman very confident in herself and her abilities. Mirko seems to believe that the heroes who join the teams are cowards, as they might rely on their teammates' strength instead of their own. Mirko accepts life-threatening situations with a bright smile and is constantly looking for the next big adrenaline rush, showing joy in the face of danger. She does not back down even when overpowered by stronger enemies, claiming that she is just getting hot. Mirko also seems to take every day of his life without regret, admitting that he would risk his life for the greater good. Despite her brash behavior, Rumi is not above helping others as she came to Endeavor and Hawks' aid after seeing their battle against Hood on the news. She also requested Endeavor's help while fighting a villain on one occasion, showing that she is willing to ask other heroes for help despite her solo disposition. He also helped the assigned team defeat Tomura Shigaraki in the Final War, where his enthusiastic and brash personality fought with someone who shared similar traits, Katsuki Bakugo, leading the two to argue on the battlefield. Mirko is able to endure extreme pain without losing focus. She reluctantly faces her own wounds. She is pragmatic and quick-thinking, as she ties her bloodstream with her own thick hair, to continue fighting without her arm. The two times he had lost his arms they were unable to stop his rampage, being able to improvise and maintain his assault. He also has great willpower and determination. She is aware that she could die at any moment because of her heroin work, so she will have no regrets if she dies after giving everything she has. When she was in high school, she was known to be a hooligan, constantly creating trouble by infiltrating fight clubs and joining fights, to the point of being expelled from her school. This continued into her high school days, where her attraction to fighting arenas led her to Underground Masquerade. Here she was able to establish her prowess as a future professional hero, with her desire to not sit on the sidelines and finish a fight to the end, earning O'Clock's respect. She also refused to receive compensation for her actions, intending to succeed alone in the future. Mirko has an athletic build with muscular arms and legs. He has tanned skin, red eyes slanted slightly inward, and straight white hair that reaches his waist. On his head he has a pair of long white rabbit ears that point upward with a slight curve. Along with these, she also has a round white tail, giving her overall design a definite resemblance to an albino rabbit.
