I imagine that the "mc" indirectly will not let the villains reach the academy, since most likely there is the fight to begin, and then the professional heroes will arrive to help, and beat the majority, just letting them escape maybe two villains? , jumping to fame the "mc" although he did not want it.
author, read this! - in jojo in the dio vs jotaro fight it is shown how the stand merged with jotaro for a while and he flew in the air, wouldn't it be great if you did this in the future ?, completely merge the stand with the user, doing that no longer exists, but the "mc" would retain all the skills such as stopping time, plus he would have the strength of his stand, his speed and his ability to fly. - Also if the stand exists, there could be the mask of the immortality of the mad doctor, besides that you could introduce the hamon. Like the hamon was recently discovered, but very few people in the world know it, but it would be controlled by a secret society of humans who have no powers, they developed it to defend themselves against those who have powers. - The "mc" would rediscover the hamon, since he knows how to train it, it would be great, you could also introduce the plot of how someone who should not have information about the hamon knows it and uses it, which could bring problems to the "mc", But this would solve it without much problem, it would be great!
