An idea just struck me while playing Skyrim:

Spoiler:

Apparently neither Tsubasa/Mariko nor Miichan knows what lies on the other side (in the same way some of us look at the afterlife).

Suppose the Kirara have the additional physics-bending capacity to teleport a Nova Center into a parallel world or dimension, and if true, I was thinking that if Nagisa (and possibly with Chieri) indeed is transported by the Kirara into that plane of existence, and discover many other Novae alive and well, I'll not be surprised if she comes face to face with Acchan and tries to convince her to return.
