Aizawa had to punish two of his students, Bakugo and Midoriya, for fighting outside of the student dormitory late at night, although the first punishment of house arrest and cleaning the dormitories didn't seem to get through to the two teenagers because theu had been caught fighting late at night once again. This time, Aizawa had sent the two to the nearby beach that had been being used as a big trash can, and their punishment was Bakugo had to clean up the right side of the trashed beach while Midoriya had to clean up the left.
