Rumi is a woman with dark skin and medium height. She has almond-shaped red eyes with long, defined eyelashes, and straight white hair that reaches her thighs, with bangs that extend to the left side of her face. Despite being slender and curvy, she also possesses a lean, athletic, and well-defined physique, especially in her arms and legs. Due to her Quirk, Rumi has long, white rabbit ears pointing upwards above her head, along with a small, round, white tail, giving her an overall resemblance to an albino rabbit.

Her superhero costume consists of a white, sleeveless bodysuit with dark purple detailing on the shoulders and waist, a large yellow crescent moon design across her chest, and a single thick metal plate encircling her abdomen. She wears purple thigh-high boots that match the bodysuit, with additional plates around the heel and toes, making her feet resemble those of a rabbit. She also wears a pair of thick white gloves with long cuffs, sporting small triangular protrusions on the edges.

During the attack on Jaku General Hospital, part of his left forearm was crushed and his right shin was pierced by a High-Class Nomu, while the tip of his right ear was cut off.

After the war, she obtained a prosthetic left forearm and right leg, which are interchangeable should they be destroyed. She also has a small, inconspicuous scar under her left eye and a large scar on her left thigh.

Rumi is tough and always speaks her mind, even if it causes conflict, and respects those who do the same. Rumi seems to believe that heroes who join teams are cowards, as they might be relying on their teammates' strength instead of their own. As a heroine, she proves to be very fearless and independent, freely traveling throughout Japan while bravely confronting any villain she encounters.

Despite her impetuous demeanor, Rumi doesn't shy away from helping others, as when she assisted Endeavor and Hawks after seeing their battle against Hood on the news. She also asked Endeavor for help when fighting a villain on one occasion, showing that she doesn't refuse to ask other heroes for help, despite her individualistic nature.

She also assisted the team assigned to defeat Tomura Shigaraki in the Final War, where her overly zealous and impetuous personality clashed with someone who shared similar characteristics, Katsuki Bakugo, leading the two to argue on the battlefield.

Rumi faces life-threatening situations with a radiant smile and is constantly seeking the next big adrenaline rush, smiling even in the face of danger. She doesn't back down, even when overwhelmed by stronger enemies, claiming she's just warming up. Rumi also seems to live each day of her life without regrets, admitting she would risk her own life for the greater good. Her great devotion and bravery have even earned her the respect of Endeavor, who vowed to finish Rumi's work and defeat the villains in her place when the Rabbit Heroine became incapacitated.

Rumi is able to endure extreme pain without losing focus and faces her injuries with reluctance. She is pragmatic and quick-witted, able to staunch bleeding with her thick hair to continue fighting without an arm. To fight in the Final War, Rumi was willing to sacrifice her injured limbs and replace them with prosthetics without hesitation, opting for this rather than undergoing lengthy rehabilitation. The two times she lost her arms were not enough to stop her relentless attack, and she was able to improvise and maintain her offensive.

During elementary school, she was known for being a troublemaker, constantly causing problems by infiltrating fight clubs and participating in brawls, to the point of being expelled from school. This continued into high school, where her attraction to fighting arenas led her to the Underground Masquerade. There, she was able to demonstrate her skill as a future Pro Hero, with her desire to not be left out and finish a fight from beginning to end, earning O'Clock's respect. She also refused to accept any compensation for her actions, intending to achieve success on her own in the future.

• As the No. 5 Pro Hero, Rumi is more powerful than most other Pro Heroes. Her hearing is exceptional, allowing her to locate her target even amidst minimal noise. She has also demonstrated the ability to multitask, attacking, dodging, and gathering information about enemies simultaneously.

During the early stages of the Paranormal Liberation War, Rumi fought alone against several High-Level Nomus for an extended period, incapacitating some and decapitating one. However, once the Nomus were fully stabilized, she was easily subdued and waited to die before deciding to take the Doctor with her.

Later, during the Final War against the villains, Rumi was chosen to join the team of heroes and assist Izuku Midoriya in the battle against Tomura Shigaraki, despite the disadvantages she suffered in her fight against the Nomu, which further demonstrates her strength as a heroine. Although Izuku's arrival was delayed, she managed to contain the enhanced villain along with the other heroes present and, in a fit of rage, her blows were strong enough to make the villain stagger and bleed. However, as soon as Tomura evolved into his final defense form, she was quickly defeated with a single blow.

• Enhanced Strength: Rumi has proven to possess exceptional physical strength, being able to easily defeat several Nomus and destroy the enormous metal gate protecting Kyudai Garaki's secret laboratory. Notably, she was able to momentarily incapacitate some of the High-Level Nomus and decapitate one of them.

• Enhanced Speed: In conjunction with her level of physical strength, Rumi possesses equally impressive speed. Her speed allowed her to reach Kyudai's laboratory in just a few minutes, remaining largely unaffected by the Nomus who tried to stop her.

• Enhanced Dexterity: Rumi has demonstrated remarkable control over her limbs and body, as seen when she fights multiple High-Ends.

• Enhanced Agility: Rumi demonstrated unique agility.

• High Pain Tolerance: During the attack on the hospital, Rumi's left forearm was crushed and she was forced to have it completely amputated, but she continued to fight intensely without problems. She kept moving even while in pain.

• Master of Hand-to-Hand Combat: Due to her Quirk, Rumi primarily uses hand-to-hand combat to subdue and incapacitate villains. Thanks to her strong legs, she favors kicks in her fighting style, combined with incredible speed and the ability to gain momentum by jumping from one point to another.

• Enhanced Instincts and Intuition: As seen during the Heroes' attack on Kyudai Hospital and against the High-Level Nomus, Rumi demonstrated extremely sharp instincts and intuition, being able to detect the grave danger that Tomura represented, despite him being clinically dead.

Rabbit (Usagi): Rumi's Quirk grants her the attributes and abilities of a rabbit. This gives her incredible leg strength, allowing her to jump and kick with extreme force; she can even destroy large chunks of the ground with a single stomp. She also has excellent hearing thanks to her rabbit-like ears and possesses animal instincts that alert her to nearby dangers.

Final blows • Luna Ring (Runa Ringu ?)踵月輪: Rumi uses her incredible leg strength to kick multiple targets simultaneously while performing a somersault in the air with her legs extended.

• Luna Fall ( Runa Fōru ?)月墜蹴: Rumi swings her foot downwards while above her opponent, propelling her target straight to the ground beneath her feet with a powerful kick.

• Luna Tijeras (Runa Tihera ?)月頭鋏: Rumi mounts her opponent's head and grips it firmly with her legs before twisting the body, pulling with all her superhuman strength on her legs to tear off the opponent's head and then smashing it on the ground.

• Luna Arc (Runa Āku ?)踵半月輪: Rumi raises her leg and delivers a powerful axe-shaped front kick against her opponent.

• Luna Rush (Runa Rasshu ?)満月ルナ乱蹴: Mirko advances towards her opponent and strikes them with a series of powerful kicks.

• Prosthetics: After losing her limbs in the Paranormal Liberation War, Rumi received a strong and durable prosthetic left arm and right leg, which greatly assist her in battle. After losing her right arm in the Final War, she receives another prosthetic. The prosthetics vary according to the needs of the moment, as in battles she uses prosthetics with built-in weapons.

• Weapons: Rumi typically equips her prosthetic arm with long-range weaponry. The combat capabilities of her left arm were first demonstrated during the Gollini Invasion, where it was able to fire a large laser from the palm of her hand. In the Final War, it was destroyed during her fight with Tomura and replaced with a multi-barreled weapon with rapid-fire capability. After that, she is seen with a normal-looking right arm and a large, Bullet Bill-like accessory on her left.

• Rumi's surname contains the kanji for "rabbit" (兎, usagi?) and "mountain" (山, yama?). Since her given name, "Rumi" (ルミ, rumi?), is written in katakana, it does not have a kanji reading.

• The moon emblem on his outfit and his rabbit-like design may be references to the Moon Rabbit tales. This is reinforced by the fact that his special moves contain the word "Luna," which means Moon.

• Rumi ranked 32nd in the 7th National Popularity Poll.
