I'm pretty sure some of the characters whose endings haven't been explained will eventually be told in the afterstory. After all, this is just the ending of the main story. There are still some things left unexplained. So I hope the side stories will be explained more clearly.
Also, this is actually a bittersweet ending. I can't deny that I really wanted Penelope to return to her world and be able to repair her relationship with her family there. Then I could see her finally healed and happy with her family. And somehow, maybe after everything is over, she can return to Callisto's world. Or who knows. I just want everyone to have a happy ending. Even Penelope in the real world.
