Mirko

Miruko is a dark-skinned woman of average height. She has narrow crimson eyes with long, defined eyelashes, and long straight white hair reaching her thighs with bangs that part to the left of her face. While slender and curvaceous in frame, she also sports an athletic and well-defined build, especially in her arms and legs. From her Quirk, Miruko has long white rabbit ears pointing upwards above her head, along with a small and white round tail, giving her an overall resemblance to an albino rabbit.

When Miruko was in middle school, she was known to be a hooligan, constantly starting trouble by infiltrating fight clubs and joining in the 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 the Underground Masquerade. Here she was able to establish her prowess as a future Pro Hero, with her desire not to sit on the sides and finish a fight all the way through. She also refused to take any compensation for her actions, intending to make it big all on her own in the future.

Miruko is tough and always speaks her mind, even if it causes confrontation, and she respects those who do the same. Miruko seems to believe that heroes who join teams are cowards, as they could just be relying on their teammates' strength rather than their own. As a hero, she proves to be very fearless and independent, freely traversing Japan while bravely facing any villain she comes across. Despite her brash demeanor, Miruko isn't above assisting others

Miruko embraces life-threatening situations with a bright grin and is constantly searching for the next big adrenaline kick, smiling in the face of danger. She does not back down, even when she is overpowered by stronger enemies, claiming to only be getting warmed up. Miruko also appears to take every day of her life with no regrets, admitting she'd risk her life for the greater good. Miruko is capable of enduring extreme pain without losing focus and faces her own wounds reluctantly. She is pragmatic and quick thinking, able to think on the spot.

Rabbit: Miruko's Quirk gives her the attributes and abilities of a rabbit. This grants her incredible leg strength, allowing her to jump and kick with extreme force; she can even destroy large chunks of the ground by thumping her foot. She also has excellent hearing thanks to her rabbit-like ears and possesses animal instincts that alert her to nearby danger. The moon emblem on her costume and her rabbit-like design might be references to the tales of the Moon Rabbit. This is furthered by her special moves all containing the word "Luna", another word for Moon.
