GIant god incident? Is that another happened off screen during the time skip thing? I feel like author might have done too many of those and it's going to take years to get the readers caught up.
I guess Araki reconsidered having gang all be killers. Still I feel like leaving Key and Laem alive could have consequences. Assuming Key can remember anything with her catastrophic brain injury. Not a fan of Rohan coming back but I guess he is the only old world callback we have in this part.
