Probs next endgame raid stuff will be based around the ppl in black hoodies ( forgot their names ) and zodiark.
Cuz it wouldn't make any sense to make a completely new super ultimate end of the world iconic bad guy right after they finished the coil story line.
Probs they pop up at the end and be all like mysterious and stuff and say things like
Zodiark this, zodiark that, things are almost ready blah.
Then we get to enjoy coil all over again except it would be called the binding coil of zodiark. Lol
Same routine, different appearance and name.
Is your body and soul ready?
