Nightwatch

When Izuku was told he was quirkless his dreams to be a hero seemed out of reach. At the age of 11, he had his dreams crushed by his idol. When he was 12 his mother died in a fire, blaming the heroes for not saving her. The heroes had just stood there watching the burning apartment but did nothing. It was then that Izuku gave up being a hero if it meant not saving lives when no one watched, so he decided to become a vigilante. After a couple of years, Izuku is the No. 1 vigilante in Japan. After a few years of being a vigilante Izuku is added to a chat made up with UA staff members. Izuku will meet some characters before he did in canon.
