Miruko (Rumi Usagiyama)

Rumi is a dark-skinned woman of above average height. She has red narrow eyes with long, defined eyelashes, and 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 a lean, athletic and well-defined build, especially in her arms and legs. From her Quirk, Rumi 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.

Her hero costume consists of a sleeveless white leotard with dark purple trim around her shoulders and waist, a wide yellow crescent moon design over her chest, and a single thick metal plate wrapped around her midriff. She wears purple thigh-high boots to compliment her leotard, with more plating around the heel and toe areas, making her feet look like those of a rabbit. She also has a pair of thick, white gloves on her hands with long cuffs, sporting small triangular protrusions around their edges.

Rumi is tough and always speaks her mind, even if it causes confrontation, and she respects those who do the same. Rumi 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, Rumi isn't above assisting others as she came to the aid of Endeavor and Hawks after seeing their battle with Hood on the news. She also requested Endeavor's help while fighting a villain on one occasion, showing that she isn't unwilling to ask for help from other heroes despite her solo disposition.

Rumi'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. Brash, confident, tough, competitive, helpful
