A character from [[Boku no Hero Academia]]. A professional hero with "rabbit" quirk, granting her various rabbit-like abilities such as immensely strong legs, capable of jumping at a great height, and superhuman hearing ability. Her civilian name is [b]Usagiyama Rumi[/b]. 

She is depicted as a [[dark_skin|dark skinned]] or [[tan|tanned]], [[toned|athletic]] [[rabbit girl]] (albeit her fanart frequently depicted her with [[muscular female|muscular]] body instead) with [[white hair|white]], [[long hair]]. While under hero duties, she wear a [[white leotard]], which when combined with her organic rabbit ears and tail can make it appears as if she's wearing a playboy bunny outfit.

Mirko was named after Mirko "Cro Cop" Filipovich, a now retired [[MMA]] fighter and Kickboxer, best known for competing in [[Pride Fighting Championships]] and the [[Ultimate Fighting Championship]].

Due to a localization error, "Mirko" is sometimes inappropriately spelled as "Miruko". When he was fighting in Japan, "Mirko" had to be translated as "Miruko/ミルコ" as Japanese does not have an independent "R" sound (the kanji らりるれろ are roughly pronounced ra-ri-ru-re-ro). Western manga translators who did not know the reference unintentionally retranslated the faulty original translation.
