I wasn't too impressed by this episode by the low animation quality, though that might just be the animation style plus standard quality file size. Overall, the series to me was like "wtf" in a good way. I'll be giving the series a few more episodes before I decide to drop it or not, though it has a good premise, I can't see it being more than another miko series revolving around exorcisms, high school life, and hijinks with relationships.
The episode was pretty funny I suppose since the hero's life just got turned upside-down and has to live with an ignorant girl/god, with an arrogant but perky personality to boot. "Even gods have to use the toilet," - I chuckled at that line. (I'd rather much prefer the heroine as her real god mode... she exudes this maternal feeling that makes me feel nice and fuzzy on the inside.)
