Izuku Midoriya is the main character of My Hero Academia. While lacking a Quirk at birth, he manages to attract the notice of renowned hero All Might and is now a student at UA under the tutelage of the famous hero.
Izuku is a quiet, polite young guy. Because he was ridiculed as a child for being born without a Quirk, he is initially timid and bashful, especially around Katsuki. After being accepted into UA and facing Katsuki in Battle Training, he gained confidence and courage.
Izuku is a hard worker with a strong will. In spite of his inability, he will sacrifice his own safety to rescue others’ lives. Even though it’s not his business, Izuku will always try to help someone in need. It’s rare for Izuku to get caught up in his thoughts and start mumbling to himself.
