After All Might's fight with All for One at Kamino Ward, he tells Principal Nezu that he is retiring from hero duty and will be devoting himself to being a U.A teacher. Nezu has concerns for All Might's well being and calls on an old friend he had encountered in his youth. With her help, Nezu hopes to keep the Symbol of Peace alive and well to enjoy retirement. He asks her to keep watch over All Might in case his enemies plan to use this time to once and for all kill the Symbol of Peace.
