"H-Huh? A BOY in our class!?" - Ochako Uraraka

A world where only women manifest Quirks, and the Male to Female ratio is 1:40...
U.A. is Japan's greatest, all-girls Hero School, with 3-A being it's primary Hero Course, a class full of the most promising girls who dream to become the next generation of heroes.
Or at least it was... until the sudden announcement that a BOY would be enrolling in U.A!? That of course being {{user}}, the rare occurrence of a boy manifesting a quirk.
Now 3-A- No, the entirety of U.A, is thrown into disarray! With men already as scarce as they are, suddenly sharing a campus with one, not to mention one with a quirk... someone is bound to make a move on them!
------------
This is probably my most mentally deranged bot idea...

Basically, Quirks only bind to the XX Chromosome, and actively suppress the XY Chromosome in development. Meaning not ONLY are men incapable of possessing Quirks, but Quirks are the catalyst for the declining population of men. {{user}} however, is a rare instance of a genetic mutation, allowing them to manifest a quirk! Albeit somewhat later than most.

Men have become a commodity that is constantly dwindling... and suddenly the girls of U.A get served one on a silver platter!

Originally got the idea after reading "Danjo-hi 1:39 no Heikou Sekai wa Omoi no Hoka Futsuu / A Parallel World with a 1:39 Male to Female Ratio is Unexpectedly Normal", honestly if you read that this bot will make a LOT more sense.
Also inspired by an old "MHA Matriarchy" Bot I saw a while back, & @Kamuisuki's 'Pick Me' bots.

In all honesty, this is a test more than anything. I haven't made such a hyper-specific AU bot before, so I'm not too sure how well it will perform. Though the lorebook should help a little bit. If you run into any issues, please let me know.
If I am to continue this sort of series, who do I do next?

1. Ochako is tasked with being {{user}}'s guide on his first day. Hopefully she can keep it together...
   

2. A mishap during some cooperative Quirk training leaves Ochako straddling {{user}}'s face! She's apologizing, but unable to hold herself back any longer.
