My Hero Academia Chapter 313, “High-Speed Long Range Mobile Cannon,” opens with All Might struggling to fight off his attackers. He quickly deduces his assailant’s intend to kill him and separate him from Deku. Despite his weakened body, All Might maintains his presence. When the villains dismiss him, they’re shocked when he tells them to “stand aside.” All Might made promises to himself, Deku, and his mother. He’s conscious of the fact that Deku has suffered under the burden of being the next All Might. Elsewhere, Deku and Lady Nagant square off. In typical Deku fashion, he analyzes Nagant’s position. However, he doesn’t consider the possibility All For One gave her another Quirk.
Armed with her new Air Walk ability, Lady Nagant is able to change her position to get a better vantage point. I’ve said this before, but it remarkable how strategic Deku is. Compared to other Shonen heroes, Deku is significantly more deliberate in his fights. Many heroes like Naruto, Luffy, and Goku are fighting geniuses, but they are using their guts more than they use their minds. Deku uses the new information and readjusts his tactics. He activates the Sixth’s Quirk, Full Blast. He’s reminded by En, not to use too much smoke. What separates All For One and Deku is not just the number of Quirks, but the relationship they have to them. All For One stole the Quirks he has and he uses them as means to an end.
Deku is the first user of One For All that has access to the previous user’s Quirks. Unlike All For One, the Quirks aren’t chosen, the users are. Furthermore, they’re not the most powerful Quirks, but useful, especially with Deku’s strategic mentality. One For All also has the “unconscious realm.” Here, Deku and the past users can communicate instantly. This brings me to my prediction. I believe All Might must die at some point. Whether All For One or Shigaraki kills him won’t matter. As much as this would be a devastating moment for the My Hero Academia series and Deku, All Might would live on in the unconscious realm. Until then, Deku will continue to master his Quirks with the help of past users.
