When Midoriya Izuku took to the streets, he had expected many things. Attacks from villains, assassins sent by All for One to capture him, but a confrontation with the beautiful ex-hero Lady Nagant ends in a way that he never would have been able to predict. This is a fic I found on ao3 written by M_Writer_Of_Stuff. All credits go to him I just wanted to move this onto Wattpad.

Ever since being taken in by the Hero Public Safety commission at a young age, all she's known is training and her new code name, Nagant. But it was all for a good cause. She was sure to get a position as a hero in the near future, so there was no need to be discouraged. Nevertheless, the USJ incident made it clear that UA may need help, so Nagant was offered a position as a student, seeing as she was fifteen. How will her new classmates and environment affect her?
