as promised, a release after my translation. this is the last one though, don't hope for more anytime soon.
by the way, there's only one last tankoubon that hasn't uploaded, which is this
https://book.dmm.co.jp/detail/b235antab00067/?dmmref=bookmark&i3_ord=1&i3_ref=list
but there are still many doujins, colored chapters and short stories which are unavailable at dmm and other dl sites. i hope someone can get it and scan it...
