Nobody remembers Izuku after he got hit with a quirk, though only some people do. Izuku is a very timid, reserved, and polite boy. Even though Izuku was born Quirkless, he manages to catch the attention of the legendary hero All Might, due to his innate heroism and a strong sense of justice, and has since become his close pupil, as well as a student in Class 1-A at U.A. High School. All Might passed on his transferable quirk to Izuku, making him the ninth and current holder of One For All.
