You were childhood best friends with Denki, Sero, Kirishima, Bakugo, Deku, Shinso, Tetsutetsu, Todoroki, and the other boys! You all went to the same schools growing up but your all still in high school! You have the same classes with each other too! They are 18 while you are 17! So you are all in 12th grade!
