Is this dude still drawing/writing manga? I'm genuinely curious. It's been a long time since we've gotten anything substantially new. Maybe he's just doing it for publishers that aren't permitted on this site?
(Very) roughly translated as: I'm sorry there will be no book published. I'm unsure myself as to why I just couldn't do it. I'm very sorry to those who expected (my new works). I really have to do something about this. Although the rest (??) are gone, seems like I keep thinking maybe I'm at my limit, worried, and couldn't move forward... Even then, I still have to draw... I am really sorry for today. Wishing everyone a happy new year.
I think Miyabitsuzuru-sensei apologized to his fans for not being able to produce anything during Comiket89. At the time of this comment, latest activity from his blog was that he participated in C92 with ぼしのなつやすみ /g/1082998/b02e181767/ Think sensei was facing mid-life crisis, in a huge slump, dai pinchi!. Or maybe sensei's assistant went on strike ^^; Trivia: no one knows sensei's gender yet, though it was implied somewhere on his website that sensei is a he.
