My Hero Academia fans are on the edge of their seats as the last battle between Izuku Midoriya and Tomura Shigaraki is set up in chapter 380 of the manga. Even more worrisome is the fact that Deku’s battle duration is limited to just five minutes because to his employment of the Gearshift Quirk. Despite the fact that chapter 380 of My Hero Academia doesn’t reveal how much time Midoriya has left in this countdown, readers are well aware that the series is coming to a close. However, many supporters believe that combining the Quirk Fa Jin with Gearshift may help Midoriya get a speedier victory versus Shigaraki, so they are attempting to figure out how he could set himself up against Shigaraki inside the five-minute time limit. The Following Problems It’s probable that Deku’s time restriction will be updated in My Hero Academia chapter 380, and that we’ll see him become desperate with Fa Jin.
Fa Jin’s Methodology
From My Hero Academia Chapter 380, fans have known that the key to using Fa Jin is to do routine, repeated actions in order to build up kinetic energy, which may then be saved for later use. This is analogous to the earlier version of the One For All’s Quirk, which involved the storage of immense amounts of electricity. To produce several short bursts of speed and power, the user can release only a fraction of their stored Fa Jin energy at a time. When combined with this facet of One For All, Fa Jin becomes exponentially more powerful.
One of the clearest examples of this boost in strength is when Midoriya uses it against Lady Nagant in the chapters before My Hero Academia chapter 380. With the help of Fa Jin’s stored energy and Blackwhip’s momentum boost, 45% of One For All’s power was able to achieve strength on par with 100% of its power. More impressively, it did so without doing as much damage to Midoriya’s body as would have been the case had he used the full might of One For All. That is to say, without really using the “full force” of One For All, Fa Jin permits Midoriya to keep fighting for far longer than he would have otherwise.
Defeating Shigaraki with the aid of Fa Jin?
With what we now know about Shigaraki and his newly awakened body from My Hero Academia chapter 380, it’s possible that using Fa Jin effectively might aid in the fight against him. More intriguing, though, is the potential for synergy between Fa Jin and Gearshift.
By enabling the user to alter the rate at which objects accelerate through space (in defiance of the rules of inertia), Gearshift may simulate the Blackwhip’s might. Nevertheless, this explanation hinges on a few essential assumptions, the first being that Gearshift may be used on the user’s body in addition to its surroundings.
This also implies Midoriya has enough energy to use Gearshift on himself and that doing so won’t reduce the amount of time he has remaining to activate the Quirk. It’s possible that combining Fa Jin and Gearshift will have negative effects on his health. That’s especially so when you realise that the user’s oxygen depletion is Gearshift’s primary problem. Assuming that Deku’s cells respond to Gearshift’s increased cellular activity, his oxygen consumption should rise accordingly if he uses the technique to speed up his body’s movement.
This is a huge risk for Midoriya’s health, but it is necessary to properly include Fa Jin in the struggle against Shigaraki. Despite the dangers, having Fa Jin on your side in the battle against Shigaraki would be a huge boost. As of My Hero Academia Chapter 380, Shigaraki’s downfall is very certain if he allows Deku to recreate the 100% power of One For All without hurting his body. If the foregoing is accurate, then Midoriya’s physical health might be in grave jeopardy if he continues to use the Quirk.
