Rumi Usagiyama in "Wing Hero: Hawks"

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 No. 5 Pro Hero.[2]


Rumi has an athletic build with muscular arms and legs. She has dark skin, red eyes which are tilted slightly inwards, and straight white hair reaching down past her waist. On her head, she has a pair of long white rabbit ears pointing upwards with a slight crook. Along with these, she also has a round white tail, which gives her overall design a definite resemblance to an albino rabbit.

Her hero costume consists of a sleeveless white leotard with a dark purple trim around her shoulders and waist, a wide, yellow crescent moon design over her chest, and two thick metal plates on 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 white gloves on her hands, with long cuffs, sporting small triangular protrusions around the edges.



Rumi is tough and speaks her mind even if it causes confrontation,[2] and she respects those who do the same.[3] 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.[2]

Overall Abilities: As the No. 5 Pro Hero, although little has actually been revealed about her strength, Rumi can be presumed to be more powerful than most other Pro Heroes.

  • Enhanced Strength: Rumi has proved to possess incredible physical strength, being able to easily defeat several Nomus and to break down the huge metal gate that kept Kyudai Garaki's secret laboratory.[4]
  • Enhanced Speed: In conjunction with her level of physical strength, Rumi possesses an equally impressive speed. Her speed allowed her to reach Garaki's laboratory in just a few minutes, being barely slowed by the Nomus that tried to stop her.[4]


Rabbit: 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 also destroyed large chunks of the ground by thumping her foot.
