This is not a japanese girl, she's not half japanese either. It doesn't matter what the retarded mangaka "intends", you can't draw a cute white girl then call her japanese. I'm not buying it. The argument about hair color being done to distinguish different characters in a black and white medium is such a reddit tier argument, japs just want it both ways, it isn't hard to figure out.
