I just came to a realization.

Gunbuster and Tengen Toppa are connected by more than maker and themes. It's the SAME DAMN UNIVERSE.

Humans fought the Space monsters in the first gunbuster. The Space monsters were after the humans because they were evolving too fast, and therefore, putting the universe in danger. Spiral energy and evolution go hand in hand. But wait. In Diebusterm we discover that humans were evolving into space monsters, the topless. These humans protected life throughout history. But maybe, someday, something defeated them, or they realized that through their evolution, they would stop the universe. That is why the first humans became the anti spirals. After that, tengen toppa.

The thing is, The anti spirals were the first humans. And Nono was reborn in Nia.
