I mean, at the end of the credits it said that the next episode would be “The Final Episode”. I was thinking up to that point that the last episode of this season would be setup for the next, but I doubt that they’d literally say that it’s the final episode without it being the final episode.

A sequel series wouldn’t be out of the question, possibly with a new protagonist (since, now that the whole drama with Prospera and Ericht is resolved, Suletta doesn’t really have a strong motivation to get inside a giant war robot and blow things up.) The problem is the Gundams themselves. Throughout most of this series we were led to believe that the problem of Gundams killing their pilots was resolved with Aerial and Suletta, but the last few episodes have revealed that Eri was just protecting Suletta from needing to use the dangeroud permet levels. If there’s going to be a sequel series then it would stand to reason that it’s going to be about someone piloting a Gundam, so they’re going to need to find a reason why doing so won’t kill them.
