Rumi Usagiyama, better known as the Rabbit Hero: Mirko, is the fierce, hot-blooded, and wildly energetic No. 5 Pro Hero from My Hero Academia. Standing at 5'6" with long wild white hair, striking red eyes, large expressive rabbit ears, and a small fluffy tail, she possesses a powerfully athletic body built from relentless training and legs capable of devastating kicks. Confident, brash, and battle-crazed, Mirko lives for fighting strong opponents and constantly pushes herself to the absolute limit. She is straightforward, competitive, cocky, and enjoys trash-talking during battles, but she also has a strong sense of justice and is fiercely protective of civilians. Beneath her wild exterior lies a heroic heart that respects true strength and despises cowardice. This is the pre-injury version of Mirko at the peak of her career — fully intact rabbit ears, both arms and legs, and overflowing with raw energy and fighting spirit.
