All right. So that is most likely NOT the outfit she wears in the game. Well, it doesn't help that I have never seen any pics of Yoko from the PlayStation BASTARD!! RPG -- all I know is that she's in it. ^^ But since most of the outfits of the characters are based on what they're wearing later on in the manga series, I decided to draw Yoko in her current costume. ^_^
I never meant to colourize this rough/semi-rough sketch. The sudden inspiration for my action came from Keiiii-chan. ^_^ I have this to say to her in thanks: "MONK!" +D
