As Izuku arrived at U.A. for his third day he noticed that the gate was blocked by reporters, all of whom were shouting questions at the student trying to get by. Izuku walked up to the crowd attempting to enter the campus unnoticed when a very eager reporter thrust a microphone into his face berating him with questions, "what's it like being taught by the number one hero? Is All Might a good teacher?"
Izuku then proceeded to state in a very monotone voice, "I wouldn't know, I'm in Gen Ed."
The reporters then immediately left him alone, almost running to go and harass other students. Izuku then began to make his way through the gate when he spotted Iida and Uraraka being surrounded by reporters and walked over to them and loudly said, "hey guys. We should get to class, they only want to talk to kids in the hero course," while giving them a subtle wink and pulling them into the school.
Once safely through the gates, Uraraka said, "thanks for helping us out, Izuku. But why did you say we weren't in the hero course?" One of the reporters overheard this and began to move forward to get the answers to their questions, she attempted to step through the gate but it slammed shut leaving her inches away from a large metal gate nearly a foot thick.
Izuku then replied to Uraraka's question saying, "because they wouldn't have left you alone if they knew you were in the hero class."

They then made their way to class arriving just in time to take a seat before the bell went off and Aizawa, their homeroom teacher walked in. He made his way to the front of that class before stating, "sorry for the sudden announcement, but today you'll pick a class president. Also Midoriya you'll need to attend a meeting after school to discuss what happened during yesterdays battle training."

Everyone burst into excited talking many shouting out their desire to be class president and making claims that they couldn't follow through on, meanwhile, Izuku was trying to figure out what the meeting would be about. The class's yelling was silenced by Iida when he suggested they vote for president, Aizawa okayed this idea before climbing back into his sleeping bag while the students got on with it.

After all the votes were tallied up, Izuku voted for Iida as he had no desire to be the class representative, it was decided that Iida would be president and Momo Yoayorozu would be Vice President, gaining 3 and 2 votes respectively.

Later in the day Izuku, Iida and Uraraka are sat eating lunch together when the female friend posed a question to the group, "hey I forgot to ask but why do you two want to be heroes?"
Iida promptly answered first asking, "do you know the Turbo Hero: Ingenium?"
At this Izuku begins mumbling about how he employs 65 sidekicks at his agency in Tokyo before coming to the realisation that, "So you're related? Probably his brother based on the age difference."
"Yes. He is my older brother, he leads people with his unwavering adherence to the rules, a truly beloved hero. It is my admiration of him that drives me to be a hero, to hold up the Iida legacy," Iida answered with a passion the others hadn't seen yet.
Uraraka then chipped in, "wow that's so cool. Izuku, what about you?"
Izuku puts on a bright smile and says, "I've always wanted to help people, even before I found out I was quirkless. Although a lot of people have doubted me or even outright mocked me for it I never gave up, I will be a hero. The first Quirkless Hero!" Izuku then said in a quieter voice, "and prove everyone wrong. How about you Uraraka, why do you want to be a hero?"
"For money," Uraraka states nervously, "it's not as noble as your reasons but my parents run a construction company and business has never been great, so I want to become a rich hero to provide for them." She ended her statement with more passion and confidence, truly believing in her goal.
"I think that's a great reason, not only are you being practical, but your also helping people while helping your parents," Izuku said while giving an encouraging smile, "anyway what do you think this meeting's going to be about after school?"
"I don't know, probably to make sure you're okay and maybe to see whether they need to punish Bakugo for being so reckless," Iida answered right before a loud alarm cut into their conversation.
The trio jumped to their feet and grabbed the attention of a passing third year asking them what was going on, they were told that it meant someone without authorisation got onto the campus and that it hasn't happened before while they've been there. They were all then dragged along in the flood of students trying to evacuate when Izuku was pressed up against the large windows making it very easy to see that it was only the reporters and that both Aizawa and Present Mic were dealing with them.
Izuku came to the conclusion that the crowd needed to calm down before anyone got hurt and came up with a plan. He pushed his way through the currents of students making his way over to his friends before telling them his plan.
After about a minute Iida was floating above the crowd, thanks to Uraraka's quirk, he then activated his engine quirk sending him careening into the wall above the exit door in a pose reminiscent of the stick figure on an emergency exit sign. Iida then yelled gaining most people's attention and said, "everyone calm down. If you look outside you'll see that it's just the press. This is U.A. behave in a way befitting this great institution." After being berated on their conduct by Iida the crowd calmed down and exited in an orderly fashion leaving Iida, Izuku and Uraraka in the doorway. Iida was helped to the ground by the two others before following after the other students.

Later after school had ended Izuku said goodbye to his friends before being escorted to his meeting by Aizawa. On the way, Izuku asked, "hey Aizawa sensei, what's this meeting about then?"
He was answered after a moment of silence with, "it's probably better if you hear it from him." Aizawa then opened the door and guided his student through it.
Izuku walked through the door feeling quite nervous, this feeling then skyrocketed when he was met with 7 sets of eyes all belonging to pro heroes. In the meeting was All Might, Principal Nezu (a small white bear-mouse), Recovery Girl, Vlad King (class 1-B's homeroom teacher), Present Mic, Midnight and Cementos, as well as Aizawa who directed Izuku to an empty seat and sat next to him, almost protectively.
All Might started the meeting off by saying, "Young Midoriya, I'm sure you know this meeting is about the training exercise yesterday, we were hoping you could answer some questions about what happened."
"Yeah... yeah. I can do that," Izuku said, stuttering over his words a bit.
"I was wondering young Midoriya, why did you not dodge young Bakugo's attack?"
"What do you mean, All Might?" said Izuku quite confused by his question.
"What I'm asking is why you stood and took the blast head on instead of trying to dodge? Were you trying to prove something or simply froze in fear?"
"Oh. No, I made the decision not to dodge to limit how much damage I took. I wasn't trying to prove anything, I'm not fast enough to successfully dodge a blast that size and by trying I would have exposed myself to the blast more. Instead, I tried to block my vital organs and head to mitigate the damage caused by the blast." Answered Izuku slightly mumbling towards the end.
Principal Nezu then spoke, "Recovery Girl can you offer any insight as to whether Izuku was correct in his decision to block rather than dodge?"
"I believe he was probably correct in his assumption that he wouldn't have dodged in time and would probably have sustained more severe injuries," was Recovery Girls answer.
All Might then addressed Izuku again saying, "unless you have any questions young Midoriya, you're free to leave."
"Actually, I do have one question. Why are you asking me why I didn't dodge and whether it was a stunt to prove something instead of questioning Katsuki about why he ignored a direct order not to use a reckless attack and attempting to intentionally harm another student?" Izuku asked feeling a little annoyed by this whole meeting, "I get that I'm Quirkless and some of you probably don't think I deserve to be in the hero course or that it's not possible to become a hero but you don't have to intentionally make it more difficult for me than any other student." Izuku then left the meeting with his head held high leaving the teachers speechless as he called out the number one hero. Once Izuku got down a couple of hallways he slumped against the wall and had a small panic attack about how he just spoke to a group of pro heroes who are also his teachers.

After about twenty minutes of sitting on the floor trying to even out his breathing, Izuku heard footsteps coming up to him. Looking up he saw Aizawa walking up to him, he was expecting the worst thinking that they might expel him right now for the way he spoke to All Might, although the more rational voice in his head was telling him that nothing he said was true. Aizawa then crouched down in front of him and said, "I want you to know I agree with you, it was unfair of All Might to question you about your reaction and not Bakugo for his reckless actions." This made Izuku smile a bit and beginning to wipe the tears away from his eyes. "After you left we were discussing what you told us and came to the conclusion that due to the position you were in you made the most rational decision to reduce injuries to yourself. As for whether or not you're in trouble you're not." He then stood beginning to walk away saying, "it takes a lot of guts to stand up for yourself like that. I'll see you in class tomorrow."
Izuku picked himself up and went home thoroughly exhausted from his first few days at U.A. but eager to continue on his path to be a hero.
