Just finished fast-forwarding through Mayoi Neko Overrun episode 7.
If you like completely random settings for giant piloted and possibly combining robots fighting, then even if you don't like what this anime is about, you can watch this episode.
Besides the chara design of a few characters, ABSOLUTELY NOTHING FROM THE NORMAL ANIME WAS KEPT.
In my case, that lead to fast-forwarding to see if the joke ended (but it didn't (IMG:[

There should be no sequel or prequel though, consider it an OAV.
