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. Izuku is 16 years old.
