Aizawa, not fully believing that someone had the nerve to talk back to him, remained silent for a moment before responding. "... What was that, brat?"
Kumagawa didn't let his smile falter, even under the fierce gaze of the Pro Hero. [I was just saying that these physical tests are completely pointless.] he answered with a shake of the head. [Although I can't speak for everyone, I'm sure that there are a few among us whose Quirks don't allow us any form of physical augmentation, nor any other form of advantage such as Bakugou-san's explosive propulsion. In the end, you are basically making a subtle effort to weed out anyone who would count as a side-character, despite how effective their Quirk may be.] jabbing his thumb towards the floating pair of clothes, he continued. [That girls Quirk is obviously some type of invisibility. Quite handy when it comes to spying on villains, but I doubt it will help her to run faster.]
At his reasoning, some of the students began murmuring amongst themselves in agreement of Kumagawa's assessment. However you looked at it, Aizawa was giving them an unfair challenge.
The Pro Hero's eyes narrowed slightly as they targeted the disrespectful teen. "Listen brat..."
[And I'm sure that if you had to go through the same initiation as us, then surely you would have been expelled as well. Because I fail to see how your Quirk would be able to help you out in a situation like this. Unless, you decided to sabotage all of your fellow classmates. Right, Eraser Head?]
Suddenly Izuku had a flash of recognition. "Wait, you're Eraser Head?!"
"Eraser Head?" repeated another student.
"Who's that?"
"Few people even know his name! He's a real underground hero!"
"Apparently he finds the popularity that comes with being a hero to be disruptive to his work."
Ignoring that murmurs of his fellow students, Kumagawa pressed on as he approached Aizawa. [So you're that kind of person after all. Just like the world, you arbitrarily decide that there are those who are destined to be less-than others. People who are not cool. People who are not strong. People who are not just. People who are not beautiful. People who are not cute. People who are not pretty. People who are not smart. People who are not talented. People who are not lucky. People who are not worthy. People who are not likable. People who are not winners... People who are not heroes.] as he grew closer, Kumagawa's smile slowly distorted into a sneer. [Don't get me wrong, that is how the world works. There are those among us who have lost long before they even try. There are people who are not cool, strong, just, beautiful, cute, pretty, smart, talented, lucky, worthy, likable, winners, or heroes. This is just the natural order of things. The 'have' and the 'have not'.] Kumagawa kept stepping forward until he was right in front of Aizawa and staring straight into his eyes. [That is something I have no problem with. Where I do take offence however, is when a human takes it upon themselves to decide the worth of another human... You are overstepping your bounds Aizawa-sensei. Trying to take on a role beyond your capability, beyond your right.]
Aizawa was heavily tempted to expel Kumagawa on the spot, but his argument was making it hard for him to do so. The rest of the students were getting restless and if he didn't handle things carefully then he'd have a full-blown riot on his hands. And despite his threat of expulsion, he couldn't very well get rid of all of them on the first day. That would be a PR nightmare for U.A. That, and Endeavor would be pissed if his son got expelled. He needed to watch his tongue and choose his words carefully. "Listen kid," he started as he leaned in and whispered so only Kumagawa could hear. "If you're trying to ensure you pass by making my job harder, then congratulations. Back off and I'll let you skip the test."
[Hmm?]
"Quit stirring up the hornets nest right this instant. If you stop now then I can still salvage this situation."
Kumagawa's normal smiled returned for a moment, much to Aizawa's relief, but the sneer quickly returned in full-force. [Unfortunately for you, there exists only one person who has the authority to order me around. And you are most certainly not her.] he replied.
For a moment, Aizawa felt he was in the presence of something far more dangerous than just another aspiring hero. The teen in front of him exuded an overbearing pressure of dread. Someone his age should not be able to pull off the look he was giving him.
[Just kidding~!]
And just as abruptly as it had appeared, the dark atmosphere suddenly vanished, and Kumagawa's normal smile returned.
[I'll take you up on your offer, Aizawa-sensei. Although I wish I could have gotten a better deal for everyone, I will just take what I can get. It seems that once again, I couldn't win.] he said as he turned and walked back over to the group.
Aizawa grit his teeth in annoyance before letting out a sigh of relief. "Just get the hell back to the classroom. We'll talk more later."
[Whatever you say Aizawa-sensei!] Kumagawa responded as he left.
Returning his hard gaze to the rest of the class, Aizawa picked up where he left off.
