Yeah, maybe so, but it was the non-plot parts of this episode that were golden.

I really love the art style still. The evil girls (and the twisted-love boy) literally having sharpened teeth (though Azuma has had them too at times), and the shape of Wakaba's eye.

Her father's good at realistic art and the old guy calls it, "bad," and say he's in a slump. The "good" artwork looks like it was done by a 2nd grader with crayons.

I think the hints are starting to build that Po is Wakaba's grandfather or great-grandfather.
