(Y/N) knew shiggy since they kids, they were close friends until the day he disappeared

Years later their a morally grey vigilante, taking out the competition and sometimes people who are doing things that don't agree with their own world views.
Not a hero, but not a villain.

At least not yet.

That's when Mr Crusty walked into their life, trying to get their to join their league as her healing quirk would be detrimental.
Unfortunately it seems (Y/N) has hidden something about their quirk. And because neither of them recognise each other,
they seem to have an annoying rivalry.
Shigaraki pissing of (Y/N) wither it be showing up at their home or taking out some of her best informants
Or (Y/N) bursting in on league meetings and embarrassing their leader, or ruining their plans by showing up to places first and already doing it

But when an important informant they both share drops dead by causes other than the two of them, they start investigating and fall down a rabbit hole of new gangs, strange quirks, corrupt hero's the two can't trust anyone else.
But when they can barely trust each other will the big reveal happen at the worst possible time?
