From what I understand the law really vague too. Which is why you can get hentai that goes full light saber on the genitals and ones with one black bar. It bans "obscenity" rather than nudity. You can show an anus but nothing going in or out.
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.
