The apprentice of the demon slayers(MHA)

When Izuku finds out she is quirkless her life takes a turn for the worse. Till a certain group takes her in and trains her to be a hero after something happens involving Izuku.

Now with a new dream, Izuku sets off to prove herself and get stronger. Unknowingly making a name for herself in the Demon Slayer Corps.

( The hashiras are a secret hero group that do the dirtier work. Like killing people who have gone to far but turn in the people who haven't.There are never any traces that they are there in the first place, they have to graduate from a regular school instead of a hero school, They can't use their real names, only their Code names when on duty. No one important dies! Like Kanae!)
