Mayoko Okino is the wicked witch of the east from Zone-00
Zone-00 has such amazing artwork and character designs that its quite intimidating to even phatom trying to cosplay or cos test anyone from the series unless your super tall and lanky CLAMP style characters.
I did this on a whim. Took apart an old NANA wig and threw together some extensions to replicate her braids and wow. This happened.
