Rumi Usagiyama in "Mirko, the No. 5 Hero"

Rumi Usagiyama ( (うさぎ) (やま) ルミ Usagiyama Rumi?), also known as Rabbit Hero: Mirko (ラビットヒーロー ミルコ Rabitto Hīrō Miruko?), is the current No. 5 Pro Hero.[5]


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.

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.

During the Jaku General Hospital raid, part of her left forearm are crushed and her right shin is stabbed by a High-End Nomu, while the tip of her right ear got sliced off.[6][7] In the aftermath of the War, she obtained a prosthetic left forearm and right leg, which are interchangeable in case they get destroyed. She also possesses a small faint scar under her left eye and a massive scar on her left thigh. She also cuts her hair to just below her jaw and adorns a new black belt with her hero costume.[8] During the Final War, her right forearm is bitten off by a mouth on Tomura Shigaraki's arm growth.[9]



Mirko at the Billboard Chart

Rumi declares that she'll beat every villain she comes across.

Rumi is tough and always speaks her mind, even if it causes confrontation,[5] and she respects those who do the same.[10] 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.[5] 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.[11] 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.[12]

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.[6] 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.[6] 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.[13]


Overall Abilities: As the No. 5 Pro Hero, Rumi is more powerful than most other Pro Heroes. Her hearing capability is outstanding, as she was even able to locate her target through minimal noise. She was also shown to be capable of multitasking, as she simultaneously attacks, dodges, and concludes information about the enemies.[6]

During the initial stages of the Paranormal Liberation War, Rumi fought against several High-End Nomu unaided for an extended period, incapacitating a few, and decapitating one. Though once the Nomu were fully stabilized, she was easily overpowered, and fully expected to die before deciding to take the Doctor down with her.

Later, while fighting in the Final War against the villains, Rumi was selected to join the Hero team to assist Izuku Midoriya in the battle against "Tomura Shigaraki", despite the handicaps she suffered in her battle with the Nomu, a further testament to her might as a hero. While Izuku's arrival was delayed, she single-handedly managed to hold back the enhanced villain, in a rage-fuelled rampage, her blows were strong enough to make the villain stagger. Though once "Tomura" evolved into his final defense form, she was quickly cast aside with a single blow.

  • 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.[14] Remarkably, she was able to momentarily incapacitate some of the High-End Nomu and sever one of their heads.[6] 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.[7] 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.[14] She was also fast enough to keep up with the High-End Nomu,[6] but once they began to stabilize, Rumi was unable to land any more blows on the High-Ends.[7] 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.[6][7]
  • Enhanced Agility: Rumi has shown to have unique agility.[6][7]
  • 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.

Mirko defeating Nomus with ease.

Rabbit ( (うさぎ) Usagi?): 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.

Ultimate Moves

  • Luna Ring (踵月輪 (ルナ リング) Runa Ringu?): Rumi uses her incredible leg strength to kick multiple targets simultaneously as she performs a cartwheel in the air with her legs extended.[6]
  • Luna Fall (月墜蹴 (ルナ フォール) Runa Fōru?): 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.[6]
  • Luna Tijeras (月頭鋏 (ルナ ティヘラ) Runa Tihera?): 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.[6]
  • Luna Arc (踵半月輪 (ルナ アーク) Runa Āku?): Rumi raises her leg and delivers a powerful front-facing axe kick on to her opponent.[15]
  • Luna Rush (満月 (ルナ) 乱蹴 (ラッシュ) Runa Rasshu?): Mirko rushes towards her opponent and pummels them with a series of powerful kicks.[9]
