After the defeat of All For One, Class 1A returns to UA high as class 1B. It is upon this year that a new transfer student comes to class 1B, named Kusari. Upon learning his strange and strong powers, Deku takes him under his wing as a student. It is this that will lead Kusari to possibly be the most powerful being to ever live and become a famous hero, or become and villain, stuck deep in the mud of greed and sorrow. Either way, in the end, it is up to Deku to teach Kusari well, and not let him fall to the path of darkness.
