What if Fuyumi was a pro hero?
So Touya/Dabi “failed” as an experiment to surpass all might, so Enji kept having kids until Shoto have both quirks.
So what if Fuyumi had both quirks or had hero potential?
I’m assuming Natsu and Shoto would just be sibling for Fuyumi and Touya (Dabi wouldn’t exist as he wouldn’t crash out that badly) while Fuyumi does pro hero work.
And considering in canon she’s a teacher, maybe she’s a U.A teacher either by merit or by being endeavors kid or both. Maybe Shoto is still in U.A because he wants to be a hero like his older sister.
And since Enji obsession isn’t that bad seemingly as Fuyumi came sooner and his goal is faster then with Shoto in canon, he’d be strict at most and probably not abusive (he only because that way where Touya was losing his shit when Shoto came around).
So yeah, I’d say it’s a fun AU. And maybe she’s the heir of the endeavor agency someday with a hero name that changes depending if she has her dad’s quirk or not in the AU.
What are your two cents?
