Mirko (Rumi Usagiyama)

Rumi Usagiyama (兎山 ルミ, Usagiyama Rumi), professionally known as the Rabbit Hero: Mirko (ラビットヒーロー ミルコ Rabitto Hīrō Miruko) or simply Mirko (ミルコ), is a supporting character in the My Hero Academia franchise.

She was the number five hero operating in the nation of Japan and the top female one. Her quirk, Rabbit, gave her the attributes of a rabbit including incredible leg strength and superhuman hearing. She was always eager to deliver punishment on evil-doers and was willing to sacrifice her own life for the betterment of society.

Mirko is voiced by Sayaka Kinoshita in the Japanese version of the anime and by Anairis Quiñones in the English version of the anime.

Appearance - (As a fully grown woman, Rumi Usagiyama stood at five feet and two inches tall. Her red eyes were tilted slightly inwards and her long white hair flowed freely down her back to her waistline. She had an athletic body with muscular arms and legs and a shapely figure. Her white eyelashes were particularly long and her skin was tanned. As her quirk was a mutant type, it affected her physical appearance by bestowing her with a pair of long white rabbit-like ears pointing upwards with a slight crook and a short white fluffy tail similar to a rabbit's. Her white hair, ears and tail coupled with her red eyes gave her a resemblance to an albino rabbit.

Her hero costume consisted of a slim-fitting sleeveless white leotard with dark-purple trimmings around the shoulders and waist, a pair of thick metal plates on her midriff, and a yellow crescent moon-like symbol over her chest. Additionally, Mirko wore dark-purple thigh-high boots with metal plating around the heel and toe areas that made her feet look like those of a rabbit and presumably reinforced her kicks. Lastly, she adorned a pair of thick white gloves on her hands with long cuffs which sported small triangular protrusions around their edges.

During the raid at the Jaku General Hospital, Mirko's left forearm was twisted and crushed by a High-End Nomu. As she makes her way to Tomura Shigaraki's capsule, she forcibly rips off part of her long hair (after a High-End Nomu grabs onto it to stop her from moving forward) and she was left with shoulder-length hair while her right shin was stabbed by another High-End Nomu (as she attempts to destroy the capsule Tomura was in) and the tip of her right ear was sliced off.

In the aftermath of the Paranormal Liberation War, Mirko now has a prosthetic left forearm and right leg. During the Final War, her right forearm gets bitten off by a mouth from Tomura's arm growth.)

Personality - (Rumi Usagiyama placed a lot of stock in physical power and combat, which makes her a powerhouse. Nothing thrilled her more than a bare-knuckled fight between herself and skilled opponents where each person was trying their hardest to defeat their opponent. She showed respect and appreciation to those with similar beliefs such as the cage fighter Kendo Rappa. Personal strength was just as important to Mirko as a willingness to fight, as she would occasionally show disdain to those who fought in teams rather than by themselves as relying on the strength of others was a sign of weakness in her eyes.

Mirko was something of a social non-conformist who spoke her mind regardless of the situation and seemingly didn't care about the consequences. She also appreciated people who did the same, as she expressed admiration when Hawks controversially spoke his mind during the Japanese Hero Billboard Chart. She was a newer type of hero who travelled across the country rather than having a base-of-operations, further demonstrating her free spirit. In her early teenage years, her attitude tended to get her into trouble, as she would mostly follow her whims regardless of whether it got her into danger or not. That being said, by the time she was in high school, she had mentally matured slightly, as she would at least try to hide her identity when following her desires into dangerous situations.

While in hero school, Usagiyama seemed to believe that all a person needed to be a hero was power. Despite this rather crude mindset, Mirko was seriously dedicated to her hero work. Although she seemed fairly inconsiderate of others, Rumi would make sure to protect people, even at the cost of her own wellbeing. Her dedication to justice was so fierce that she honestly didn't mind if her hero work was to one day take her life. She was also willing to throw away her pride and work with others during times or crisis as she recognised that helping people was more important than her own personal feelings.)

Abilities - (A Super Move was a special technique performed by a hero or villain that allowed them to turn the tide of battle in a single move. Usually, this was done by the user focusing all of their effort into a singular attack, whether it be an application of their quirk, fighting style, or both. Although there were exceptions, Super Moves were usually unique to the heroes or villains that invented them. All of Mirko's known Super Moves focused on making particular strong combative assaults that were meant to decimate her opponents. Thus far, she has demonstrated the use of four Super Moves, each of which acted as an application of both her quirk and combative skills. Additionally, each of her known moves were thematically named after the moon.)

Quirk - (Rabbit: Mirko's Quirk, aptly called "Rabbit," gave her powers thematically reminiscent of a rabbit's abilities in the same way that Tsuyu Asui's quirk "Frog" gave her frog-like abilities. The quirk was a mutant-type, meaning its very existence changed its user's physical appearance. In Rumi's case, her Quirk made it so she had a rabbit-like anatomy consisting of red eyes, white hair, a white rabbit tail, and long white rabbit ears.)
