[Sentai]

Had a theory about the first scene of Gaim and what we know now.

Invess are created when animals ingest Lock Fruit, Lvl 2 Invess are created when humans ingest Lock Fruit. The first scene of Gaim has Baron with an army of Invess and Gaim with his own Invess army. What if what their standing on is the ruins of Zawame City and their army is all the animal and people that once lived there being overtaken by Lock Fruit and Helheim Forest?

I also think that the one chosen by Helheim is Mai, and that's why she turns into Mysterious Girl and time travels and all that. But that's an obvious one.
