"Okay, so here are the OVAs 1 & 2 of DtnK.
Original subs by Senpachi Fansubs
All translation credits go to them. They did a great job in my opinion.

In their original release, they had some artifacts showing on episode 2. As their translation was pretty solid, I thought it was a waste no to fix the whole thing, so that people like me could archive it. I asked permission to do a fixing, which they kindly accepted.
While I was at it, I took a higher resolution (720×480 -> 1024×576), fixed some minor typos I found here and there, and increased font size accordingly."
