OK, I think we can all tell that the final arc is not gonna end any time soon. What I think will happen is that the rest of the factions: The witches, other kingdoms and even elves will have a hand in destroying Lucius's goals.

I think the Clover Kingdom will lose the initial fight. I think Lucius still has one more ace in his pocket to ensure his goals succeed. A way to turn everyone into his people quickly instead of doing the flawed and tedious process of hunting everyone down and killing them. I also think this may be deadly for him and thus he'll capture Mimosa to ensure his own survival. I say this because if his plan was simply killing people, he would not need Morris. There were any number of people to kidnap or revive that could have been more useful.

When the Clover knights are defeated I believe it'll be Mars and Fana that save them. I mean we just got the undersea people back, the diamond kingdom is gonna show.

As for the bulls, I think they'll either seek out the Dryad or possibly the witch queen in order to find Asta and these people may possibly lead the bulls to a secret that can defeat Lucius in the process.

However, this is all just my thoughts on the matter. How do u like it and if you have any thoughts to add or ideas of your own, I'd love to hear em'.
