" "Wow." " Two identical looking kids exclaimed in awe.
Both of them started to shake hands and inspect each other thoroughly. Suddenly, a single claw came out of each of their hands from the knuckles.
Seeing that both of them said in unison ""Cool! ""
Then suddenly the door opened, that made the kids surprised and one of the kids dissipated into thin air.
"Wow." The remaining said in amazement, and the one who opened the looked at the kid and asked "What happened Ryō?"
"Look mom! I have daddy's quirk!" Ryō showed his mom the two claws protruding out of his knuckles.
Seeing that the women smiled and said "Isn't that good? Now you and daddy are a matching pair."
"Yay!" Exclaiming that Ryō tried to jump up and down, but he shot straight to the ceiling and collided with the ceiling fan, slicing Ryō into two.
"Ahhh" His mother let out a blood curdling scream.
"What is it?" A man with black hair and green eyes came running to the room as fast as possible.
"My baby!" His mother screamed again and went towards the two halves that were laying on the floor, but before she could reach, the two halves got up with a jump.
Seeing two identical boys, both the womens and man's eyes went wide in surprise.
The two boys looked at each other, the one on the left said "Hey you're back. Where did you go before?"
"I don't know! I got scared and disappeared, then bam we were sliced into two and I appeared again." The one on the right side said.
"" Cool "" Both of them said in unison.
"Ryō! Don't scare me like that!" Saying that the women hugged both the boys and shed some tears as her boy was alright.
The man who came in hearing the scream of the women said "So you got your quirk champ?"
"Yes daddy!" The one on the right said.
"Look!" And the one on the left showed his father the claw protruding out of his hand.
Seeing the claws, the father smiled and went towards them and hugged.
"Let's go to the doctor okay?" The father asked the boys.
"Yes daddy." The right one said.
"But we need ice cream." The left one chimed in.
Hearing that, the father chuckled and said to the mother, "Hiyori, now you have two sons to spoil."
"Mmmm~ mmmmm~ that I do, Yato!" Hiyori said and looked at her son's and asked "Can you be one again?"
"Sure." The right one said.
"No problem." The left one said.
Then both of them extended their hands, and both the Ryō's combined back into one.
Seeing the process, Yato said "Fascinating! It's like how our cells divide."
"Well, it is fascinating." Hiyori agreed with Yato.
"Now, change your clothes Ryō, we need to see the quirk doctor." Yato told Ryō.
"Okay." Saying that Ryō went to his cupboard where his clothes are slowly as he didn't want to run into the wall like he did with the ceiling.
As the three of them got properly dressed, the family of three went to the quirk doctor.
After a plethora of tests, the doctor called the three of them into his office.
Looking at Yato and Hiyori, the doctor said "Mr. & Mrs Kurokiba, your son Ryō has the quirk to duplicate himself at his own will. He also has a single retractable claw from his hands, and he has an enhanced physiology. So my advice is, make sure to train Ryō to control his enhanced physiology as he has the strength of an adult man in a four year old body, and it will grow as he grows older."
"Alright doctor, we will look into it." Yato said, and asked the doctor "What's the name of the quirk, doctor?"
"Since he can create a duplicate or clone of himself with his clothes that are too identical, we decided to name it Ditto." The doctor said smugly, as if he had done something amazing.
Yato and Hiyori just smiled at that, after thanking the doctor for his time, the Kurokiba family left the hospital and headed towards their home to enjoy this joyous occasion.
----------------------------------------
{Six Months Later}
"Ryō, wake up, it's time for training." Yato told his son while rocking him side to side.
"Five more minutes!" Ryō said.
"Nope. We have to do it on time." Yato said while taking the blanket away from Ryō.
As the only thing that kept him away from the cold was gone, Ryō slowly rose from his sleeping position and gave his father a stink eye.
Yato just chuckled at Ryō and said "Go and freshen up, we will start with running, then basic strength exercise after that it will be sparring. The usual."
"Okay." Ryō agreed.
After freshening up and doing his morning routines, Ryō went out of the house where Yato was waiting for him.
Smiling at Ryō, Yato said "Shall we start?"
"Yes." Ryō said with a little bit of enthusiasm.
Smiling, Yato started to jog, and both father and son jogged side by side for at least five kilometers. Yato and Ryō were okay to keep on jogging as they have enhanced stamina.
After that, it was basic strength exercises, like push ups, pull ups, squats, planks, sit ups, lunges etc. the repetition is one hundred each with twenty sets.
Then it was sparring section between Ryō and his clone under the direction of Yato in their personal Dojo. As Yato is a martial arts practitioner, he advised his son Ryō to have a clear mind whenever they were sparring and also taught Ryō about the discipline that a martial artist should adhere to. And Ryō adhered everything his father said, taking in everything taught by his father like a sponge.
Yato taught Ryō Judo and Jujitsu accompanied by Ryō's clone, as they found out that the clone of Ryō and Ryō are connected to a hive mind that is in Ryō. So Yato took advantage of it and started to teach one martial art to each clone.
Hiyori, on the other hand, took it upon herself to help her son's studies. She also joins the dojo to see Ryō spar against his clone, with Ryō using Judo and the clone using Jujutsu.
On a Sunday, when they were having family dinner, the news showcased All Might saving civilians as many as he can. Seeing that, Yato asked his son "Do you want to be a hero Ryō?"
Ryō who was watching the news, replied to his father's question "I'm not sure dad. Heroes get hurt right? They fight the villains and the villains hurt the heroes, they might even hurt the loved ones of the hero."
Then looking at both his father and mother he said "I don't want to see both mom and dad get hurt."

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.
