Is their any hope for season 2? The story can go further and have a happier ending,
My happy ending would be:
I was thinking of time travel Empirical arm. Future generation need help as nobody in the future was able to use Akame ga kill main characters empirical arms, that's why they are needed in the future to fight evil. They would also need esdeath powers and she decides to help because Tatsumi promise her that they will have bright future together if she helps.
Also to explain those deaths in season 1. a Future character power is to make illusions.
