Man, this is such a trainwreck that I can't even consider it so bad it's good anymore. He resented his past life for being oppressed and held down, so in this life, he lets himself get oppressed and held down. He has no qualms fighting people for performing injustices, except when injustices are aimed towards himself. I get that could just be his personality, but in that case, why give him a second chance at life for him to squander? Just because his powers are strong enough to overcome physical challenges, does that mean he's completely incapable of growing as a person? I don't want him to be excessive with it, but he needs to be able to stand up for himself some more, especially when the people trying to harass and attack him are trying to abuse their power to do it. He'd be justified in using his strength if they were trying to do the same, but he just refuses to do so.
Also, that line about not wanting him to participate because he's not a noble is such a ridiculous take. Excluding the fact that the first chapter made it seem like nobles were under the command of commoners (which was most likely just shitty writing and hopefully wasn't the author's initial intention), why would a noble even need a scholarship to begin with? Isn't the whole point of it to give less fortunate students the ability to achieve the same results as their wealthier counterparts as a reward for their hard work? He's already shown he's superior to everyone else in the exams, but because he's a commoner, which the initial proctor in chapter 2.2 said didn't matter, he just has to sit back and take it? Isn't that just going to make everyone else look worse when their lowest ranked student can run laps around them?
