We have to consider Julius's predictions. The Clover Kingdom will be destroyed and Asta will be killed. Those two things will definitely happen, I believe Our boy will die in the fight against Lucifero but the black bulls will go to the land of the rising sun to get him back. Curtosy of Yami informing them of a way.

In this case I do believe Yami will die, literally taking a shot for Asta, or just as a result of getting to weak.

In the mean time Lucifero will work on getting the rest of his power. In the process releasing the rest of of the high class devils, other than the other two Supreme ones.

While all this happens Asta soul will be on a spiritual journey, kinda like Liono from the 2011 Thundercats series. Whether Liebe is wurv him or not.. I'd prefer he'd be.

As for deaths... I predict Yami, Charlotte, Sisgoleon [I never called her that] these are the only guys I see dying right now. So what do you think?
