Curate, connect, and discover
I've been reading a lot of MP100 x MHA fics and looking at prompts and I'm absolutely in love with the idea of Quirkless Reigen faking having a quirk, maybe even running his own (not exactly legal) "hero agency" in Seasoning City and getting the most powerful sidekicks and interns possible despite being relatively unknown as a hero (also not exactly legally one). His "agency" is more focused on just helping people with whatever issues they may have be it spiritual, Quirk-related, or otherwise really.
I just think it would be interesting if maybe, one of the kids he knows (maybe Teru, even) placed really high on the UA Sports Festival and ended up dragging along other characters to Spirits and Such because that's where he ends up interning. Others are like, surely the Hero who managed to get Hanazawa to intern at his agency is super powerful and knowledgeable right? Right??
What they end up with is a sweaty man in a cheap suit (is that supposed to be his hero costume??) claiming his Quirk to be so powerful and out of this world he can't use it for most situations lest he destroy the city block or something, who gives them much needed life counseling and lectures and takes them out to help citizens with the most mundane things under the guise of "evil spirits" or "villainous plots".
He has maybe two, three employees there, though they don't have many work hours anymore, they do pop in sometimes and help the interns learn about the job, the paperwork and attitude and helping others. And thus they learn the power of customer service that it isn't big flashy fights or being super popular that makes a hero, its just being a good person and helping others.
