Goddammit, a Yotsuba thread has been up for month and I hadn't realise. i've recently been reading it again. Vol 13, will get to 14 in the future (I own all the volumes but I don't read them all at once).
Gee, the transition from 12 to 13 is kinda jarring, not just thematically, but - to keep this /c/ related - Yotsuba is way more toony, with the other characters seemingly more photorealistic (esp new ones like Grandma). As
>>3698392 put it, a lot of the fan art of Yotsuba here is quite old.
