>Nothing regarding Nyaan
To the very end, they didn't know why she existed.

All major plot points are already wrapped up to varying degrees of success, A S2 would probably be a new cast and plot just set in the universe

This show really needed like 25 eps desu with my main issue being we just didnt get enough of the characters to care (Machu vs Nyann is my main example, was supposed to be a big moment but kinda just didn't work because they never really seemed to connect with each other)

I think a more realistic option we might get would be like a short manga series based around the Clan Battles that we didn't see as well as the time spent between the characters during that time to make the friends feel like actual friends, could also throw in some other background politics such as expand on the Titans with their plans and preparation regarding Deux and the Psycho Gundam
