Miho is the defender of Old Town, and the one woman the girls of Old Town call upon to get rid of troublesome people, like cops, criminals, and abusive johns. Miho doesn't care for racial slurs (like being called a "Jap *****/****e") and will use her twin katana to "play" with anyone who calls her such names. Such play usually has her dodging her opponent's blows while hitting him (usually with contemptuous ease) in return. An assassin skilled with swords, shuriken, longbow and rollerblades, she resides in Old Town, though popular belief maintains she is not a prostitute.
Miho is tiny, standing maybe 4'10" maximum and weighing a mere 80-90 pounds. She has short black hair, a very slim figure, and dark eyes. Normally she dresses in a loose black kimono, into which is tucked all sorts of weapons. A wakizashi (sometimes two) hangs from her belt.
Nothing much is known about Miho's past, except that three years before the events of "A Dame To Kill For" she was saved by Dwight McCarthy in an attack by Tong gangsters. As Dwight himself explains to Goldie and Wendy, "three of the Tong who attacked Miho were dead by her hand. But the last two had her dead to rights. Point blank range."[ 1 ]
In the "Family Values" yarn, Dwight also remembers one incident that had to do with Miho killing a cop ("Remember what went down the last time you killed a cop."[ 2 ]). This refers to Miho killing Jack Rafferty in "The Big Fat Kill".
Miho uses Samurai swords and shuriken in the shape of the Manji, as seen in "The Big Fat Kill" and "Family Values".
Miho and Dwight have also completed a number of successful missions together and the two are good allies, if not exactly friends. Miho has since repaid Dwight for the saving of her life by saving him from drowning in the Pits of Basin City.
Frank Miller has stated in the Recut DVD that Miho and Kevin are the supernatural beings in Sin City. They are "demons". Miho is the good "demon" and Kevin is the bad.
