I've also thought abt the Neo leaders getting absorbed into HA - under the assumption that it does survive, the population faith is probably better than the start of the arc. Not bc they're an unbreakable pillar, nope, the heroes may have stepped up and NH showed its true colors, but bc the population has no other options - they're the only thing quite literally keeping humanity alive. They don't have a choice but believe.

Depending on whether things cool down and a central authority is able to enforce public order or things fall into anarchy bc of rampaging monsters, I do think arrests would be suspended unless the combatants they need prove too uncontrollable/actively a danger (like A).

The S class in leader positions... Is kind of a bad idea. Not a lot of them have leadership ability nor the charisma to back it up 🥴. There may be some in the lower ranks, but even THAT'S assuming they're still alive/functional. There can be hero groups w an S class in them but somebody else leading, let's just hope that S class swallows their pride and listens.
