I'm just your problem

(Another name based off my Spotify playlist, it's called my mixes by vance and also no u. Check em out.) (omg I feel like I'm trying to promote my mixtape, LOL!!)

A trans boy in his second year at the UA, an 18 year old speed villain with engines on his legs, and a pro hero with literal finger guns. How could they all be connected?

Here r the names:
(English + Japanese. (All in English order))

Finger gun hero: Gun Gale
速い 指銃
Hayai Yubiju

Time freezer and engine villain: Speed Runner
(he will later become a hero/sidekick to Gun Gale)
天使 飯田
Tenshi Iida
(O0O "omg they're an Iida?! Yes.)

And the trans boy:

騎士 幽霊
Kishi Yurei

(His quirk functions much like Mirio's except, he can become invisible, possess people and fly. And from the support of Mei Hatsume and his sister Kizu Yurei, he has a costume that stays on him, *again like Mirio*)
