Mimiko is a fellow cyborg herself from the M-City, she was once human before she got into a fatal car crash and the only way for the doctors to keep her alive was to replace her damaged organs with the help of machinery, thus turning her into a cyborg. Other than the eyes, no one can really tell that she’s a cyborg because she has artificial skin that makes her appearance look like a normal human.

Mimiko is an easy-going, funny, and cheerful kind of gal. But when it comes to battle for she was trained to use her programmed weapons and combat skills whenever she or her loved ones were in danger.

As you can see, Mimiko is a bit of a fan of Genos! It’s not only because he’s a metal hunk and a cyborg as well, but Genos actually saved Mimiko at one point from a monster that attacked her and ever since then, Mimiko never stopped supporting and adoring Genos from afar! She eventually got close to him and his master, Saitama, and ended up being his girlfriend!
