Izuku Midoriya, also known as 'Deku', is a quirkless boy who'd dreamed of becoming a hero. However, he gave up on his childhood dream. He was always a target for being bullied because he was quirkless, and he was unrealistic, dreaming of being a hero with no quirk. After graduating from middle school, he went to a different high school and separated himself with his childhood best friend/bully, Katsuki Bakugou, also known as 'Kacchan' by Izuku, after years of constant torment with him.
