After this episode I think they are doing it purely on purpose. The drawing scene / thing was the last straw to break the back of the suspicious camel. The warrior girl, Tokiko, tells she can't draw, and then the guy suddenly draw quite a nice picture. I wonder why they just didn't go all the way down the street and make the girl first draw a laughable picture. If that scene wasn't a reference to Bleach, combined with everything else, I don't anymore know what is.
