The Nightsiders' Hero Agency
Nightside: a term coined by KatHarkness-Katara for DC vigilantes that I thought fit Underground Heroes really well.
The Nightsider's Hero Agency is a bit of a misnomer because although Yagi is involved, it was coined in honor of Aizawa, because he was there for ALL of Class 1-A from the beginning. Although you won't see them, other yearmates were pulled in to make Nightsider's a reality.
Rolling over, Mineta Minoru huffed a disgusted sigh. He didn't want to get up, but he had to work, which meant getting up in his crappy apartment, out of his lumpy bed and starting the day early. It wasn't fair! He was working as the desk clerk for a lowbrow agency, and all his former classmates were running a high caliber hero agency famous for fielding teams that got the job done quickly and efficiently. Their support department and business managers were known for being cutthroat, cunning and their schoolmates.
(What Mineta didn't know, hadn't been close to knowing, was that Shinsou, Midoriya and a select handful of others had started Nightside to protect the Underground heroes and to play mostly by their own rules. The requirement to be considered part of the Founders was that you respected or were taught by Eraserhead or All Might. But to actually be part of the agency, in the beginning, you had to be willing to give a percentage of your earnings to Pros who weren't making money anymore. Shouta and Toshinori hadn't needed it, but their had been others, especially Eraserhead's Underground contacts, who could use an open medical wing or some cash to pay the bills.)
It was really annoying that he hadn't been able to get in, because Nightside made a lot of money, but they also trained sidekicks well. The brats that interned at his agency always complained about whoever had taken the available slots for Nightside.
(Most of those little shits never realized it wasn't simply respecting your predecessors and comrades that got you into the door. Shinsou and Aizawa had made sure there were ample opportunities for the sidekicks to explore Underground work, especially those with 'villainous' Quirks. Bakugou, Todoroki, Kirishima and Kaminari only took the most dedicated physical heroes, while Ojirou was the official 'Sifu', the hand-to-hand master who put everyone through the wringer eventually. Yaoyorozu kept a careful eye on the rich kid wannabe heroes, guiding them to the right choices while Todoroki especially kept watch on the legacies and Shinsou on the 'villains in waiting'. It was a good system, but unashamedly selective in who they took on, not wanting disrespectful little snots around Aizawa and Yagi.)
Why? Why had he, their classmate until Shinsou stole his spot, been rejected when he applied to Nightside?
(Aizawa Enya, Eraserhead's wife and the performer Thunderheart, had been the deciding test. The gentle former socialite had visited at just the right time to see if Mineta was still his perverse self. Which, no surprise, he hadn't changed. Instead of one of the team or division leaders making the decision, Bakugou had hoisted the rotten grape by the collar and tossed him into the street, the viciously powerful bastard snarling as he launched him into the air.)
Why had freaking Bakugou 'I don't give a shit just get out of my way' Katsuki been the one to toss him out? Why, for that matter, hadn't he insisted on being a team or division leader?
(Bakugou, in the years since enrolling in Yuuei had suffered and changed in ways that Mineta hadn't. He'd watched Izuku and Eijirou try to protect him, had met Enya and seen how overprotective Eraserhead was. Had realized that Aizawa was likeable because he channelled his asshole moments into being productive and was generally neutral if not pleasant. So Katsuki, having realized he fucking loved Izuku and liked and respected Eijirou, had toned himself down. Had backed away to the fringe of the group to keep an eye on the people he cared about without being obvious, having decided Deku was beyond him, now. He'd decided to be the asshole so the others didn't have to.)
Why had his life turned out like this?
(Because Mineta Minoru was a sniveling cluster of rotten grapes who couldn't see that his perversion, his open idiocy was what kept the others from reaching out, from actually liking him.)
Sighing again, stretching, Mineta Minoru got up and got ready for another day of the life he'd brought on himself.
(Not that he'd ever actually admit it.)
Enya: an indulgence in my headcanon that if Aizawa isn't married to Mic (which I doubt) he's probably got a sweet, well groomed, polite socialite who doesn't care what her family thinks of her scruffy Hero. There is a point to Enya, and Enya will show up in at least one work outside of Nightside. For visual people, she has mid-back length red-black hair, can comfortably rest her cheek on Aizawa's shoulder, is gorgeous but doesn't care about that. Sweet, like I said, her maiden name is Akatsuki. When she's not performing (she has two Quirks, like Todoroki but not quite) she's teaching Quirk control at the Akatsuki Academy for Performing Arts, which is owned by her father.
