Here's what I predict: the family head shows up, BTFOs a bunch of high rankers, says some generic shonen garbage like "Mwahaha you can't beat me! My power level is 1 billion!" Then Luslec shows up and spars with the FH to keep him busy while everyone runs away. Not sure if Ha Jinsung will survive. He might get killed off to give Bam motivation to declare war on Jahad. But either way, I can already see what's gonna happen with the rest of the story.
You would think that with all the complaining SIU does about how much he's gotta draw that he would be inclined to speed things up. But the way it's going, there will probably be another year of this battle before the arc ends.
