Rumi Usagiyama (兎うさぎ山やまルミ Usagiyama Rumi?) also known as 5th Pro Hero Rabbit Hero: Mirko (ラビットヒーロー ミルコ Rabitto Hīrō Miruko?) Rabbit (兎うさぎ 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.
