We return to Boku No Hero Academia with a chapter centered on Midoriya, who is in a meeting with the old OFA carriers. In this meeting we see all those former carriers who for decades have tried to improve the power of OFA.
This chapter is transitional, as well as the following ones, all this while the heroes are recovering from the great war they had. During this meeting, one of the old carriers mentions to Midoriya, that 4 months ago in OFA began to evolve and in this way, the consciousness of the old carriers is still united, that's why now they are all gathered there with him.
The 4th carrier goes to Deku, and tells him that he died just at the age of 40 years old, but he died of "old age", because the OFA cannot be used by "normal" people and having the OFA in his body for 18 years, completely wore out his body.
But before dying and passing the power to his successor, he was able to strengthen the OFA. However, the first bearer explains that this only happens to those people who already have a Quirk, that is, if a person who already has powers, inherits the OFA, the wear that this power will do to his body will be very large.
Therefore, the only ones who can withstand the power of the OFA without suffering the wear and tear on their bodies are those who were born without powers, as well as Deku and All-Might. This is how All-Might was able to have the OFA for 40 years without suffering the wear and tear.
This is why Deku will be the last OFA carrier, since having so many powers together, if any other person wants to inherit it, it will be very lethal for him, unless they find a person who, like Deku and All-Might, was born without powers.
The chapter ends with Nana Shimura asking Deku if he will be able to kill Tomura to end all this chaos once and for all.
