@themick:
Hero career world building would be fun but we just got an arc where the villains are going to destroy that world. So it seems poorly timed and pointless. Unless he shows the bad side to the hero society but from the heros perspective.
While that is possible in the future, I don't see it happening soon in the slightest though. That is endgame saga or post-timeskip material, not something you throw out before the second high school year. Shigaraki getting an army doesn't automatically mean that hero society is going to crumble just yet. Like typical supervillain routine, they need time to make plans and maybe pull a small stunt or two to set up a huge scheme.
The worst thing for Shigaraki, and by extension Horikoshi's writing, to do with the Paranormals is to have them quickly announce their presence to the world despite just recently covering up a town's destruction and already having their villainous tentacles ensnared around the media to subtly manipulate it to their advantage. I would argue that their greatest advantage right now is not even their numbers/strength but the fact that the public has no idea they exist yet, which has a lot of unique future suspense and tension potential that does not have to dial everything to 11 to top itself immediately. Not to mention it would make Hawks' double agent infiltration lose a lot more narrative purpose for the villains to show their cards so early.
Have the heroes investigate to find out what Shigaraki is up to piece by piece while we the audience are kept in suspense instead of just having the heroes react to them.
That and after having such a long villain-centric arc, along with Horikoshi's usual style of hopping from school arc to villain arc to repeat, it makes sense for this arc to be somewhat a breather as we get reaccustomed to the heroes' perspectives and the world's status quo again, especially before big changes happen afterwards so the stakes and plot transition feel all the more impactful. Especially after how dark the flashbacks were, so we're sure for at least some lighthearted storytelling as a palate cleanser to balance the manga's tone and make the dark moments feel more special instead of predictable or dare I say even repetitive.
And I'm always game for showing more hero society flaws. Especially front and center in an arc plotline instead of only being a cool worldbuilding detail that will only get introduced/referenced once in a blue moon or foreshadow a big development years later.
