Happy new year all. Just finishing up the 2 bonus chapters and the tankoubon bonus, then that'll be Vol.4 done.
I'll buy Vol.5 once I get paid then start working on that in a week or two.
21 should be here by the end of the weekend. Already got it cleaned, just busy tomorrow so it'll be a Sunday job. That'll cover the final episode.
Update - just joined a few 2 page images, forgot to do that before the upload. Think it'll be pages 12+21 now

It's been a consistent 1 volume/year (+/- a few months) since 2020, with the exception of 2 volumes within 2 months this year, so the author got motivated hard by the anime release. Averaged out 2 months per chapter besides volume 7, which was 2 months for a whole volume.
