Hi. Sorry for not informing you about the state of the scanlations. Here's the gist of it: I have translation of chapters 87-90 made by Zek77, Vietnamese translator who knows Japanese. You can download his translations using links below:

Unfortunately I still haven't made any progress (I've started typesetting first 20 pages of chapter 87 but it's far from over). I've been busy with RL things and when I've had some free time, working on DP wasn't that high on my list. Now I have even less free time. I wanted to finish the first chapter in the second half of September hoping that someone with more free time and skills would be willing to work on this awesome manga but that also didn't work out.
I would really love to make more scanlations but unfortunately I don't have time and it looks like it will be like that for at least a 8 more months. So if there is anyone here who would like to continue I can give you access to this blog and you can continue. Maybe I could help with some typesetting but doing whole volumes is currently out of the question.
If you want to use Zek77's translations be sure to credit him!
