So the last fighters are going to be Seigfried + Brun, after Brun does the unthinkable and sacrifices or forces Goll to fight in a desperate attempt to win.
Which may or may not back fire leading to how Seig and Brun end up fighting for humanity representing both the best and worst of both gods and humanity against an unknown foe. (A god that takes the place that Buddha forfeited?)
With the shocker being that humanity loses in some dramatic, sacrificial, participation trophy kind of way and the gods decide not to judge, cuz the respect was earned.
