Arc, Wanda, and Izuku both got into UA together and they were on the same class as Hitomi, Kyoka, Momo, and even Katsuki. They met new friends like Ochako, Iida, Mina, Kirishima, and two from other locations. 

Robbie Reyes from New York City. 

And Shuri, the younger sister of Black Panther from Wakanda. 

They did some trials in this course. Including a quirk assessment which was from their homeroom teacher, Shota Aizawa A.K.A. Eraser Head. 

Sambamhaw: If you're wondering how did that play out, well, here's how it went. (snaps his fingers) 

The scene starts outside a field as everyone was wearing gym outfits.

Students: What? A quirk assessment test?

Ochaco: But orientation! We're gonna miss it!

Aizawa: If you really wanna make the big leagues, you can't waste time on pointless ceremonies.

Students: (gaps)

Aizawa: Here at UA, we're not tethered to traditions. That means that I get to run my class however I see fit. You've been taking standardized tests most of your lives. But you never got to use your quirks in physical exams before. The country's still trying to pretend we're all created equal by not letting those with the most power excel. It's not rational. One day. The Ministry of Education will learn. Farron, you managed to get the most points on the entrance exam. What was your farthest distance throw with a softball when you were in Junior High?

Arcturus: About seventy meters.

Aizawa: Right. Try doing it with your Quirk.

Aizawa then tossed Arc a ball which he caught and he walked into a white circle.

Aizawa: Anything goes, just stay in the circle. Go on. You're wasting our time.

Arcturus: (stretches arm) You got it, teach. (thoughts) I always wanted to try this.

Blue lightning starts crackling off him and he spins around at super speed. Then, he throws and the ball goes flying off. Aizawa checks the speed tracker, and sees that it flew about 806.8 meters long.

Aizawa: All of you need to know your maximum capabilities. It's the most rational way of figuring out your potential as a pro hero.

Students: (gasp at seeing the results)

Kaminari: Whoa, 807 meters, are you kidding me?

Mina: I wanna go! That looks like fun!

Sero: This is what I'm talkin' about, usin' our Quirks as much as we want!

Aizawa: So this looks fun, huh? You have three years here to become a hero. You think it's all gonna be game and play time? (smiles) 

Idiots. Today you'll compete in eight physical tests to gauge your potential. Whoever comes in last has none, and will be expelled immediately.

The students were now on edge as it wasn't even the entire first day and already the man was planning on expelling people. They all couldn't help but collectively think the same thing.

Students: I'm in danger. 

Aizawa: Like I said, I get to decide how this class runs. Understand? If that's a problem, you can head home right now.

They soon get over there shock and most looked a bit better to do the tests, Katsuki was grinning, and Izuku was nervous as he was still trying to get a handle of his Quirk.

Ochaco: You can't send one of us home! I mean, we just got here! Even if it wasn't the first day, that isn't fair!

Aizawa: Oh, and you think natural disasters are? Or power-hungry villains? Hm? Or catastrophic accidents that wipe out whole cities? No, the world is full of unfairness. It's a hero's job to try to combat that unfairness.

Wanda: (mutters) He's really taking this seriously.

Hitomi: (thoughts, looks down in sad) Is it because I'm here? 

Aizawa: If you want to become a pro, you're gonna have to push yourself to the brink. For the next three years, UA will throw one terrible hardship after another at you. So, go beyond. Plus Ultra-style. Show me that it's no mistake that you're here.

Arcturus: (thoughts) If that's how it's gonna be, then so be it.

Aizawa: We're wasting time by talking. Let the games begin.

And so they began the games. Hitomi listed off the eight tests Aizawa had mentioned to herself, thinking about how she could use her quirk to improve her score.

Hitomi: (thoughts) Softball throwing, the standing long jump, 50-meter dash, endurance running, grip strength, side-to-side stepping, upper-body training, and the seated toe-touch. Looks like my force field will be moving around a lot. Y/N, I promise I'll make it up to you. 

(If you guys didn't see it on the villains team part, yes, she'll be forgiven and apart of the harem) 

And so they began the games. For the first few tests, a lot of students did have it easy with doing a race, a strength grip test, a long jump, and jumping side to side.

Having an uneven amount of people in the class, Hitomi had to be in a group of three with the last two students to go, them being Momo and Mineta.

Hitomi: (thoughts) If I can use a force field to propel myself forward, maybe I can knock off a few seconds as long as I don't trip...

As the three students were getting into position, Hitomi noticed Momo slipping on a pair of roller blades before moving into position.

Hitomi: (thoughts) Where did she get those?!

She shook her head, refocusing back on the track. At the sound of the whistle, Hitomi formed a force field a few feet behind her. Bringing it towards her quickly, she maneuvered her feet onto it and the force of the coming barrier launched her forward several meters. She stumbled as her feet met back with the ground, but ran towards the sensor as fast as she could, a satisfying beep sounding off as she passed. She finished at 4.58 seconds.

Hitomi Kanetsukabe! Quirk: Force Field!

This Quirk involves superheating the air within a one meter radius around herself to form plasma, which make up her force fields. She can form them around herself, or launch them to attack others. They are generally easy for her to maintain.

If she repeatedly creates force fields in the same areas, the high concentration of heat will result in varying degrees of burns.

She looked back to see Momo and Mineta pass the finish line, their scores sounding off.

Hitomi: (thoughts) That's three seconds faster than in middle school! It seems like using my force fields will be useful during the tests.

Hitomi held her hands in front of her, clenching her fists with a timid smile as Aizawa called for the class to move on to the next test. 

The fifth test was the ball throw again, and since Arc already went, he didn't have to do it again. Hitomi stepped into the throwing circle, staring at the ball in her hand.

Hitomi: (thoughts) I'll have to throw a lot of force fields at it if I want to get a better score.

A plan set, Hitomi threw the ball as hard as possible. Immediately after, she made small force fields along her arms and threw them at the ball continuously. She could see it propel forward with each hit, and in one last effort, Hitomi made one bigger force field with both her hands, throwing it with all her might.

The ball shot forward from the impact, before finally falling to gravity and hitting the ground. Aizawa held up the device which revealed she reached 152.4 meters as Hitomi's brow furrowed. 

It's not that that score wasn't impressive; it was actually three times better than her distance in middle school. The problem to her was that it was nothing compared to her other classmates.

Hitomi: (thoughts) What was I thinking? I couldn't begin to compare to them.

With Katsuki... 

Katsuki: GO TO HELL!!!

Katsuki throws as hard as he could with an explosion, blasting the ball into the air. Yup, I am not surprised how he said considering he is ballistic. 

Ochako then used her quirk to throw the ball and it just didn't come down and Aizawa held up the record and everyone saw it just was an infinity symbol and everyone looked surprised.

Everyone: Infinity?! 

Then it was Izuku's turn who was determined. He didn't want to let his down. He didn't want to let his mother down. He didn't want to let All Might down. He didn't want to let Y/N down. 

The power of One For All surged through his right arm before he reared it back... and threw. However, when Izuku was about to throw the ball, it landed normally. 

Izuku: Uh... what gives? I was trying to use it just now.

Aizawa: I erased your quirk.

Izuku looks at the teacher, and saw his scarf was moving, his eyes glowing red, and his hair standing all the way up. 

Aizawa: The judges for this exam were not rational enough. Someone like you should never be allowed to enroll at this school.

Izuku: Wait, you did what to my—(gasps in realization) Those goggles. I know you! You can look at someone and cancel out their powers. The Erasure Hero. Eraser Head!

Wanda: Now I remember. (to Arc) Didn't he and dad work together?

Arcturus: Yeah, they were stealth based heroes. So their work agencies were close.

While the students were talking, All Might and Cynthia were watching from behind.

All Might: (thoughts) Aizawa's one of those guys who doesn't like the media because he thinks they interfere with our work. And he judges celebrity heroes like me because I look good in the spotlight.

Cynthia: (thoughts) Typical of this goth hobo to treat this too much like real life. Yes, Izuku can't keep breaking his limbs, but after everything he's been through, he needs to be here. But, like he said, he runs class the way he wants.

Aizawa: You're not ready. You don't have control over your power.

Izuku: (gasps)

Aizawa: Were you planning to break your bones again? Counting on someone else to save your useless body?

Izuku: No! That's not what I was trying to do!

Izuku was suddenly grabbed by the scarf and pulled in.

Aizawa: No matter what your intentions are, you would be nothing more than a liability in battle.

Izuku: (gasps)

Aizawa: You have the same reckless passion as another overzealous hero I know. One who saved 1,000 people by himself and became a legend. But even with that drive, you're worthless if you can only throw a single punch before breaking down. Sorry, Midoriya. With your power, there's no way you can become a hero.

Izuku was shocked, but his expression changed to determined. The other students were curious at what went down as they didn't hear. But Arc and Wanda did, and Arc was holding Wanda to prevent her from attempting to kill the teacher. Said teacher stops his quirk and his scarf relaxes.

Aizawa: I've returned your impractical quirk. Take your final throw. Hurry and get it over with.

He walks away and Izuku gets back to his spot. 

Iida: I wonder if our teacher gave him some advice.

Katsuki: Probably told him to start panicking. He's done for.

Arcturus: He didn't. However, our teacher made a mistake.

Iida: What?

The One For All inheritor had to think. He had a long way to go in gaining control of his power.

Izuku: (thoughts) So I'll focus on what I can do right now!

He reared his arm back again with the ball in his hand. This time, he channeled his power into the tip of his index finger and threw as hard as he could. And as he did...

Izuku: SMMMMMAAAAAAAAAAAAASSSSSSSSSSSHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

He launched the ball into the air thanks to the force added from his fingertip, sending it high into the air as everyone watched in awe.

Arcturus: (smirk) He underestimated Izuku's quick thinking.

His throw had gone 715.3 meters, further than Katsuki's. He turned around to Shota and faced him, forcing a grin while closing his right hand into a fist.

Izuku: Mr. Aizawa... You see? I'm still standing.

Aizawa: (surprised, grins) This kid... 

All Might: (thoughts) I was worried about you, young man, but you're doing a great job. You knew you had to use One For All, but not at full power or else you'd be KO'd. So, you propelled the ball at the last possible point of contact—by sending the power of your quirk shooting through your fingertip. Minimizing the injury of your body while maximizing the throw. What the heck, young Midoriya? How did you go and get so cool? 

Cynthia: (thoughts) Just like Izuku to think smarter. Way to go, kid.

Arcturus: Sweet throw, buddy!

Rebecca: Way to go!

Ochaco: Nice, he's finally showing his true power.

Hitomi: It was incredible. 

Iida: But his finger appears to be broken now. 

Arcturus: True, but it's better than his whole arm.

Katsuki: (thoughts) What the hell was that?! If he had a quirk, he would've gotten it when we were kids! This is impossible! He's up to something. And that gravity weirdo and cat girl were involved in this. (speaking, runs to attack Izuku) HEY!!! DEKU, YOU BASTARD!!! YOU'RE GONNA TELL ME HOW YOU DID THAT OR YOU'RE DEAD!!!

Izuku: AAAAHHH!!!

Arc appears in front of him, but Aizawa beats him to it by using his scarf to restrain Bakugo and prevent the angry boy from using his quirk.

Katsuki: (strained) What? Why the hell is your damn scarf so strong?

Aizawa: Because it's a capture weapon made out of carbon fiber and a special metal alloy. Stand down. It would be wise to avoid making me use my quirk so much. It gives me serious dry eye.

Students: Too bad. That power is amazing.

Aizawa: (lets Bakugo go) You're wasting my time now. Whoever's next can step up.

Arc and Izuku move away from Katsuki but he keeps glaring at them.

All Might: Young Farron and Young Maximoff don't seem too pleased with young Bakugo.

Cynthia: They've always been like that. Arc especially looks out for his friends. He gets that from his parents.

All Might: His parents?

Cynthia: I'm surprised you didn't figure it out. He's Richard and Claire Farron's son.

All Might: (thoughts) That where I recognized him... That kid's a monster if he's Lightning's son!

(time-skip)

After that bit, they finished up the rest of the tests. Unfortunately, Izuku had to go through that with a broken finger and soon Aizawa gave his results.

Aizawa: All right, time to give you your results. I've ranked you all from best to worst. You should probably have a good idea of your standing already. I'll just pull up the whole list. It's not worth going over each individual's score.

He pulls up the list and they see Arcturus got first while Izuku got last. Said boy was worried, but Aizawa says something that surprises them.

Aizawa: (turns list off) And I was lying, no one's going home. (all students are shocked and he smiles) That was just a rational deception to make sure you gave it your all in the tests.

Momo: I'm surprise none of you didn't figure it out. I'm sorry. I guess I probably should have said something.

Kyoka, Kaminari, and Mineta: Yeah, you should have.

Sero: That was pretty nerve-wracking, huh?

Kirishima: Nah, I'm always down for a challenge.

Arcturus: (thoughts) They're wrong... He wasn't lying at all. So why did he change his mind?

Aizawa: That's it. We're done for the day. Pick up a syllabus in the classroom. Read it over before tomorrow morning. Midoriya, (hands him a slip) take this and go have the old lady fix you up. Things are gonna be tougher tomorrow when your actual training begins.

He leaves the class, and was soon greeted by both All Might and Cynthia.

All Might: Aizawa, that was a rotten move.

Cynthia: And a bit dark from you.

Aizawa: So you two were watching. No talk shows today?

Cynthia: Just making sure my kids didn't give you a headache.

All Might: "A rational deception." That's cute but you're not exactly known for being lighthearted. I read your file. Last year you expelled an entire class of freshmen students.

Cynthia: You don't have a problem with kicking kids out. Anyone you deem unworthy. You were planning to send last place home. So what made you change your mind?

All Might: I believe it's because you see the same kind of potential in young Midoriya as I do.

Aizawa: What's this about? It almost sounds like you've been in his corner the whole time.

All Might: Uh-

Aizawa: Isn't it a little early for you to be playing favorites? (begins walking) He doesn't have zero potential, I admit. If that were the case, I would have sent him straight home. Same thing with Farron and Maximoff.

Cynthia: Why them?

Aizawa: (stops walking) Cynthia, if you really love those kids, then do me a favor—make sure they don't become too much like Richard and Claire. Farron's already walking down that road. Which means the ending could be the same.

He leaves, and Cynthia was actually clenching her fist.

Cynthia: You may be a kind man in your own way... but bringing up Wanda and Arcturus's parents was low. Even for you. (thoughts) Besides, they're doing this for Y/N's sake. I should know that. 

However, unknown to them, they were being watched from a tree by an athletically-built woman with short mint green hair and sharp eyes of the same color. She wears a gray sleeveless combat suit with a mask obscuring the lower part of her face. Strapped to her back is a white quiver carrying the ammo for her bow. Accompany her suit are bulky, cream-colored boots, and a green hooded cape with a red arrow fletching pinned to the left side of the hood. On her right hand is a burgundy glove, and on her left, the index finger is wrapped in the same material.

Beros: (pulls out her phone) Y/N, this is Beros. It appears your siblings have entered UA along with Izuku, Hitomi, and Katsuki. 

Y/N: Good.

Beros: Shall I kill him for you while he's still in my range? 

Y/N: No. Live him alive for now, I want to see the look on his and Hitomi's faces when they me before I'll end their lives. Return to base for now. 

Beros: Understood. (ends call and hops off the tree) 

Chapter 2.5 ended.
