{Ryō Kurokiba; Age: 11}
"I'm Kaina Tsutsumi. Nice to meet you." A young girl with two-tone hair which is blue with pink highlights and purple eyes said out loud while standing in front of Ryō, who was leisurely walking towards his home.
Ryō looked at her from head to toe, not minding her outgoing personality, and said "I know, the new transfer student in my class."
Seeing the lukewarm response of Ryō, Kaina said "I came here so that I could join U.A."
"Did I ask?" Ryō asked back.
"No you didn't. But seeing you get annoyed is fun." Kaina said in a funny tone.
Ryō looked at her thinking 'This girl got some screw loose, I should keep my distance.'
"You know, when I was speaking with our classmates they said that you are a social butterfly. But that's not what I'm seeing now. Is there any secret?" She said to him, with the last part almost in a whisper.
"No." And he just gave a single word reply.
Hearing that, Kaina was slumped as she didn't know what to do.
Suddenly he said "I'm Ryō Kurokiba."
"Yes! And I'm Kaina, you can call me Kaina." Kaina said, regaining her lost enthusiasm.
Ryō asked her, "So why are you annoying me?."
"I wanted to know about you, as you're the only one I don't know anything about other than what our classmates said." Kaina said.
"If they told you everything about me then you should know enough to understand that I don't like anyone trying to intrude into my lonesome time." Ryō told Kaina, as some sort of warning.
"I know! I just wanted to introduce myself to you as soon as the class ended, but you left swiftly." Kaina said.
"Now that is out of the way, please leave me alone." Ryō told her.
"Okay, I understand Kurokiba. Goodbye." Saying that
After Kaina left him, Ryō released a sigh of relief as the annoyance had left him alone.
When he reached home, his mother who was waiting for him asked "Did you have fun at school?"
"Yeah, it was fun. There was a transfer student who joined us today." Ryō replied.
"Oh really. What's the student's name then?" Hiyori asked him.
"Kaina Tsutsumi. That's all I know." He replied while taking off his shoes.
"A girl huh?" Hiyori said.
"You're talking like I haven't spoken a word to the girls in my class." Ryō said with a sigh and went towards his room, and he was closely followed by his mother who ruffled his orange hair and said "That I true. Anyway, go to the dojo, dad is waiting for you."
"I'll be there in a minute." Ryō said that as Hiyori walked past his room and went towards the kitchen.
Closing the door of his room, he changed his uniform and donned the Keikogi.
Even though he had decided not to be a hero, he didn't stop practicing martial arts as it gave him a peace of mind and total control over his body that allows him to exert the required strength and speed as he desires.
'I do have enhanced strength and it has only increased after growing up like the doctor said. I had the power of an adult man when I was four. Now, seven years have passed and I'm eleven years old, and my strength has increased exponentially. I can even lift a car single handedly. So my question to you is, should I be a hero and risk getting my parents hurt, or should I be a vigilante who won't be caught in the act.' Ryō thought all of that while looking in the mirror.
Sighing, he looked to his left and a clone appeared on his left side. The clone also looked at him and said "If we can change our face or body structure, basically shape shift into something else, we can do vigilantism. Before they get us all we have to do is dissipate ourselves, they will think that we have some kind of teleportation quirk that will throw them off our tail."
Ryō looked at his clone and said "We will look into it when we are adults. Right now, we have lessons from dad."
"Is it Judo and Jujitsu again?" The clone asked.
"Nope, dad said that we have mastered those martial arts, so now that grappling is out of the way he will be teaching us Taekwondo for kicking." Ryō said as both of them went out of their room and walked towards the dojo.
Getting inside, he saw that the dojo was empty with his father sitting at the dojo master seating area.
With a smile both Ryō and his clone made a beeline towards Yato.
Yato, who had been meditating, opened his eyes, as he heard the footsteps. When he saw that it's his son, he got up from his sitting position and said "Well. As I have said before, you have mastered grappling. Next phase is kicking, for that we will be learning Taekwondo and kickboxing."
Both Ryō and clone nodded as they know that it will always be in pairs so that they could learn as fast as possible. But before they began, Ryō asked his father "Dad, if I can make more clones will you teach us more?"
Yato eyed his son, and thought 'The doctor said that Ryō can only make one clone of himself. So does that mean that doctor was wrong about my son's quirk?'
"Yes, I will teach you if there are more of you. But there aren't any more of you, are there?" Yato spoke to Ryō.
Ryō shrugged his shoulders and started to split into two more DittoRyō.
"" We can be four now dad! "" All four Ryō said in unison.
Yato was pleasantly surprised and thought to himself 'So my son can clone himself multiple times as he ages. Does that mean he will be able to make a lot of clones of himself in the near future.'
Ryō on the other hand also thought 'I got these two when I was five years old, and after every birthday I was able to create more clones. The number of clones was increasing by the power of two, so now I can make two hundred and fifty two clones of myself. But if I say that to mom and dad, they will freak out, so let's keep it this way.'
----------------------------------------
The next day, Ryō was on his way towards his school thinking about what he should do when the classes are over.
As he was thinking that, he did notice that a person was sneaking upon him thanks to his enhanced senses.
So he turned towards the person who was about to jumpscare him and asked "How are you today Kaina?"
"Awwww Damn. I wanted to see your scared face." Kaina said with a disappointed face.
Ryō chuckled at her antics and said "Well, I won't get scared anyway, so don't try it."
"It's alright, I'll do something else then." Kaina said.
Then they walked side by side to their school. Before reaching the school gate, Ryō aske Kaina "Hey, I've been meaning to ask."
"What is it?" Kaina asked by tilting her head.
"Why did you transfer to our school when it's nearing the end of the school year?" Ryō asked.
"Well! I want to become a hero! And for that I need to join the U.A." Kaina replied with a smile on her face.
"You could have joined the U.A. wherever you are in Japan right? Anyway, let's get along well." Ryō said.
"Yes! Let's be friends Ryō." Kaina said to Ryō with a big smile.
And that smile was contagious as Ryō also smiled and said "Sure, let's be friends."

Thanks for the detailed prologue! Here's a follow-up 2000-word continuation of your story, picking up from the end of the previous scene:

Chapter One: The Test Begins
The halls of U.A. High School buzzed as students exchanged whispers about the new combat instructor. Logan's imposing presence had struck a chord deep within the hearts of Class 1-A, and even the most spirited among them, like Bakugo, had been momentarily silent after his introduction. Now, they waited — some anxiously, others with fierce resolve — for their first session under this mysterious warrior.
The next day dawned crisp and clear. Morning rays glinted off the windows of the training grounds — or rather, a part of the facility students had rarely entered. It was the "Restricted Training Sector," typically reserved for upperclassmen or emergency simulations.
Aizawa led Class 1-A down the stone path that wound around the school building and stopped at a heavy metal door reinforced with shock-resistant plating.
"You've trained in controlled environments," Aizawa said, voice calm but firm. "Today, that changes. What lies behind this door isn't a battlefield we've prepared for you — it's one Logan designed. Go in expecting to be surprised."
With a click and a hiss of hydraulics, the door creaked open. Inside lay an urban warzone: crumbling buildings, overturned vehicles, smoke machines simulating burning debris, and hidden speakers emitting distant screams and explosions. It was a visceral, immersive replica of an actual crisis.
Standing at the center, arms folded, was Logan.
"Get in here," he barked.
The class stepped in, eyes scanning the chaos. Even Midoriya's encyclopedic mind, so used to categorizing threats and building strategies, faltered for a second.
Logan began to pace. "This is a simulation based on a real event. A quirk-powered terrorist group attacked a residential district. Civilians were trapped. The pro-heroes were overwhelmed. I'm not interested in who's the strongest today — I'm interested in who thinks, who acts, and who breaks."
He turned to Aizawa. "They don't know the rules yet?"
Aizawa shook his head. "It's all yours."
Logan nodded. "You'll be operating in pairs, randomly assigned. Your job? Locate and evacuate civilians — marked dummies — while avoiding or neutralizing enemy threats. You'll be scored on strategy, teamwork, and adaptability. Fail to act quickly or put your partner at risk, and you'll be pulled out."
He paused.
"And if you're thinking this is like the rescue training you've done before, think again. This time, the threats fight back."
A panel opened in the wall, revealing humanoid combat drones — tall, heavily armored, some equipped with blunt-force weapons, others with mounted stun guns.
A wave of unease rippled through the class. Even Bakugo's confident sneer twitched.
Logan raised his voice. "Pairing list is on your comms. You've got five minutes. Move."
The students' wrist-mounted comm devices blinked to life. Midoriya's eyes scanned the screen. He was paired with Tokoyami. An odd combination — but intriguing. Tokoyami's strategic darkness paired with Midoriya's analytical mind might just be the edge they needed.
Ochaco had been paired with Bakugo — a combination she clearly didn't see coming, judging by her visible flinch. Bakugo, for his part, scoffed and turned away, muttering about "not babysitting."
Kirishima found himself with Yaoyorozu. Todoroki, surprisingly, was paired with Mineta — a move that clearly frustrated both of them for different reasons.
Logan observed the reactions carefully. Each choice had been intentional.
"Simulation starts in three... two... one..."
The lights dimmed, the speakers blared the sound of collapsing buildings, and the class scattered into the mock urban warzone.
---
Midoriya & Tokoyami
"Let's head east," Midoriya whispered, crouching behind a collapsed bus. "We need high ground. Maybe from that half-standing apartment building we can get a layout."
Tokoyami nodded. "Dark Shadow will scout ahead."
As the spectral bird zipped forward, Midoriya took a deep breath. "We have to expect traps. The dummies may be in unstable areas, and the drones won't go easy."
They moved fast, passing a charred car and diving into the ground floor of the building. Dust rained down from above. The ceiling looked ready to cave, but they made their way to the second floor, where Tokoyami halted.
"Three heat signatures," he murmured. "Two drones, one human-sized figure."
Midoriya's brain raced. "Split them. I'll distract the drones with Full Cowling. You get the dummy."
Tokoyami hesitated. "And if the building collapses?"
Midoriya's grin was determined. "Then we don't make it a prolonged fight."
Moments later, Midoriya shot from the stairwell in a green blur, landing a smash on the first drone's shoulder. The metal arm crunched under the blow, but the second drone spun and fired an electric bolt that grazed Midoriya's leg.
He hissed in pain but kept moving.
Tokoyami darted past, scooping the dummy from under a fallen beam. "Got it!" he shouted.
"Retreat route is clear!" Midoriya called.
They escaped through a side window, sliding down a pile of rubble just as the second drone gave chase — only for Dark Shadow to engulf it from above, immobilizing it.
---
Ochaco & Bakugo
"This is NOT going to work," Bakugo growled as they ran down a smoke-filled alley. "You slow me down."
"I'm not here to slow you down, I'm here to save people," Ochaco shot back, face stern. "So maybe if you worked with me—"
An explosion tore into the wall beside them. A drone stepped out, larger than the rest, its arms ending in dual hammers.
Bakugo wasted no time, launching into the air. "Stay outta my way!"
His blasts hammered the drone, forcing it back, but it adapted quickly, parrying his attacks and striking back. Ochaco moved fast, touching nearby rubble with her quirk and launching it at the drone's head. It staggered, and Bakugo capitalized, blasting through its chest.
"Fine," he muttered, "not totally useless."
Ochaco rolled her eyes. "High praise from you."
They found the dummy wedged between two cars, under a smoking beam.
"I'll lift it," Ochaco said. "Use your blasts to slide it out."
They worked in tense silence, but it worked. As they carried the dummy to the extraction point, Bakugo murmured, "Not bad. Still not fast enough."
Ochaco only smiled.
---
Elsewhere: Chaos and Progress
Kirishima and Yaoyorozu made an efficient team. She created a reinforced stretcher for the injured dummy, while he shielded her from two drones using his Hardening quirk like a battering ram.
Mineta and Todoroki, by contrast, struggled. Mineta's nerves got the better of him, and he nearly triggered a tripwire that Todoroki had to freeze mid-spring.
"You need to calm down," Todoroki said, voice even.
"I wasn't built for warzones!" Mineta whined, sticking his pop-off balls on the walls to delay a drone.
"Adapt," Todoroki said, freezing an entire alleyway behind them. "Or you'll fail."
Logan watched all of this from a raised observation booth with Aizawa beside him. On his screen, each student's vitals, movements, and performance were tracked in real-time.
"They're better than I expected," Logan admitted.
Aizawa nodded. "They've been through a lot."
"Still too green. Some are relying on quirks too much. Others are breaking under pressure."
"You'll change that."
"That's the idea."
---
Conclusion of the Trial
One hour later, the final buzzer sounded. The lights rose. The battlefield fell silent.
Students regrouped at the extraction point, exhausted, bruised, but mostly intact.
Logan descended from the booth.
"No speech," he said. "You saw what it's like when things go wrong. You either adapt or you fall."
He scanned the faces of the class. "Some of you worked like pros. Others froze. All of you need work."
Midoriya opened his mouth to speak, but Logan held up a hand.
"Don't thank me. Don't try to analyze it yet. Go rest. You'll need it."
As the class filtered out, murmuring to one another, Aizawa approached Logan.
"You pushed them hard for a first session."
"They need it. You know that."
Aizawa sighed. "Yeah. I do."
Logan turned to look at the retreating students. "There's potential there. Real potential. We'll see if they can live up to it."
And so began the true test for Class 1-A — a gauntlet of new challenges, new fears, and, ultimately, growth. With Logan leading them through the crucible, the road to becoming true heroes would never be the same again.
