In case this is interesting for anyone, I got physicals for most of the media in the franchise (LNs, manga, and DVDs): Physical Media Megathread - #814 by 暁のルナ
I’ll probably finish book 12 tonight. So hopefully will add impressions of 11-12 later on as well. For now I’ll just say that 11 provided some much needed character growth for Yumi, and I’m finding her more enjoyable to read now (she’s gained some more self-confidence, and is actually speaking up about things)). Also finding Sachiko more tolerable now. Have a somewhat different impression of Touko this time around as well.
Anyway I’ll add thoughts via the usual details tags, once I’m done later
