I actually expected to be more "meh" about this but this still managed to be a good chapter: pace is still relatively high, like "ok she was gone for a while let's get this shit going", and funny overall especially those glasses. And man, that thumbs up Ouka in the sky is hilarious no matter how many times I see it.
I do think it was a nice touch to actually make her fail to get her to come back. It's a good opportunity for character growth.
