Izuku Yagi is the son of Inko Yagi and Toshinori Yagi who is also known as the number one hero All Might. At the age of 4 Izuku and his twin sister Izumi Yagi went to the quirk doctor to find out their quirks. In the end Izumi's quirk was an A rank telekinetic while Izuku was a C rank quirk. Due to this his father started to pay less attention to him and more on his sister. Luckily his mother and his sister still support his dreams to become a hero. But what none of them know was the true potential of his quirk.
