Rabbit Hero: Mirko (Rumi Usagiyama)

Age: 27 Gender: Female personality: 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.

She also assisted the team assigned to take down Tomura Shigaraki in the Final War, where her overzealous and brash personality clashed with someone who shared similar traits, Katsuki Bakugo, leading to the two arguing on the battlefield.

Mirko ready to continue fighting Rumi's fierce and combative attitude. Rumi 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. Rumi also appears to take every day of her life with no regrets, admitting she'd risk her life for the greater good. Her great devotion and bravery even earned her the respect of Endeavor, who vowed to finish Rumi's work and defeat the villains in her stead when the Rabbit Hero was left unable to fight.

Rumi is capable of enduring extreme pain without losing focus, and she faces her own wounds reluctantly. She is pragmatic and quick thinking, as she was able to bind off her bloodstream with her own thick hair to keep fighting without her arm. In order to fight in the Final War, Rumi was willing to sacrifice her injured limbs and have them replaced with prosthetics without a second thought, choosing to do so rather than go through time-consuming rehabilitation. Both times she had lost her arms were not enough to halt her rampage, and she was able to improvise and keep up her assault.

When she 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, gaining the respect of O'Clock. She also refused to take any compensation for her actions, intending to make it big all on her own in the future.

Physical appearance: Rumi is a tan-skinned woman of average height. She has narrow red eyes with long, defined eyelashes, and straight white hair reaching her thighs with bangs that extend 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.

Powers: Enhanced Strength: Rumi has proved to possess exceptional physical strength, being able to easily defeat several Nomus and to break down the huge metal gate that kept Kyudai Garaki's secret laboratory. Remarkably, she was able to momentarily incapacitate some of the High-End Nomu and sever one of their heads. However, after they started to stabilize, she was quickly overwhelmed by them to the point that she was prepared to die and decided to finish off Doctor Garaki to take him with her. Later, her strength proved capable enough to force back the rapidly evolving "Tomura", though she was quickly defeated once "Tomura" progressed to his final defense form. Enhanced Speed: In conjunction with her level of physical strength, Rumi possesses an equally impressive amount of speed. Her speed allowed her to reach Kyudai's laboratory in just a few minutes, being barely slowed by the Nomus that tried to stop her. She was also fast enough to keep up with the High-End Nomu, but once they began to stabilize, Rumi was unable to land any more blows on the High-Ends. Later her speed was shown to be enough to outpace "Tomura" in battle, but her speed quickly proved inadequate to outpace his final form. Enhanced Dexterity: Rumi has shown to possess remarkable control over her limbs and body, as seen when she fights multiple High-Ends. Enhanced Agility: Rumi has shown to have unique agility. High Pain Tolerance: During the Hospital Raid, Rumi's left forearm was crushed, and she was forced to cut it off completely yet continued to engage in extremely intense combat without issue. She kept moving even though she was experiencing pain. Even after sustaining major injuries, she was still able to seemingly ignore the pain enough to achieve her objective and destroy Tomura's container. Master Hand-to-Hand Combatant: Due to her Quirk, Rumi primarily relies on hand-to-hand combat to restrain and incapacitate Villains. Thanks to her strong legs, she heavily favors kicks in her fighting style, matched with incredible speed and the ability to build up momentum by jumping from one spot to the next. Enhanced Instincts and Intuition: As seen during the Heroes' raid against Kyudai's hospital and against the High-End Nomus, Rumi showcased to have greatly sharp instincts and intuition, with her having been able to detect the severe danger Tomura possessed despite him being medically deceased.

Quirk: Her 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.

Ultimate Moves: Luna Ring: Rumi uses her incredible leg strength to kick multiple targets simultaneously as she performs a cartwheel in the air with her legs extended. Luna Fall: Rumi swings her foot downwards while she is above her opponent, driving her target straight into the ground beneath her feet with a mighty kick. Luna Tijeras: Rumi mounts onto her opponent's head and grips them tightly with her legs before twisting her body, pulling with all of her superhuman leg strength to rip her opponent's head cleanly off and then smashing it into the ground. Luna Arc: Rumi raises her leg and delivers a powerful front-facing axe kick on to her opponent. Luna Rush: Mirko rushes towards her opponent and pummels them with a series of powerful kicks.
