Thoughtless { Villain Deku x Reader }

When they were 6 years old, Izuku and (Name) promised each other that they'd become heroes. At the age of 10, (Name) had to leave to go study aboard, but that didn't change her dream, as well as Izuku's dream, on studying in the hero course school "U.A Academia" where their hero graduated from.
At the age of 15, (Name) came back to her hometown where she entered the hero course and surprisingly got accepted. But one thing that struck her was that her best friend, Izuku Midoriya has been missing one year after she left, and that Musutafu has been getting frequent villain attacks; like twice a month.
What happens when (Name) accidentally encounters the Villain League? and sees her best friend on the other side?
