One was pretty confused.
A villain had just been killed right in front of them—a concept so foreign, so far removed from their world, that the thought hadn't even crossed their minds before. Now, faced with the brutal reality, they realized they had to confront the issue head-on. Especially the heroes. They couldn't let the students process this alone.
"Why did he just kill him…?"
The question came from one of the Class 1-B students, the boy with the welding quirk—Juzo Honenuki, though many just knew him by his hero name. His voice was unsure, disturbed.
Vine stood silently with her hands together, murmuring a quiet prayer for the villain's soul.
(Author's Note: So guys, I just want to say something real quick. I don't know how to write some of the characters' names properly, and I feel like that's normal for a lot of people. So from now on, for characters I'm unsure about, I'll refer to them by their hero name. Like how "Vine" is the divine hair girl from Class 1-B. If you don't recognize someone by their hero name, you'll have to Google them yourself. Also, I'm gonna call Shigaraki dust man from now on because other than a couple of times I'm sick of writing his name)
"I mean… I know he was a villain, but he didn't deserve to end up like that," Chargebolt said, his voice more hesitant than usual.
"Oh no…" Mineta groaned, grabbing his head. "That idiot! Now when the heroes show up, they'll arrest him instead of the villain!"
A lot of students found themselves agreeing with that thought. That is, until Bakugo finally spoke.
"You morons," he snapped, his tone sharp. "There were no heroes yet. No one existed to stop that guy."
His words made many students freeze. Slowly, their eyes drifted back to the screen.
"And even if there were heroes back then," "they'd have done the same thing. After all, that bastard earlier did the exact same thing," he finished, referring to the first scene they'd all seen near the beginning of the episode.
It was Shigaraki—leader of the League of Villains—who had reminded them of that. He'd made sure to bring it up with an unsettling grin, and that moment still lingered in their minds.
The students flinched slightly as they remembered, but it was the pro-heroes who reacted the strongest. Their eyes narrowed and locked onto Shigaraki with silent fury, sending him a glare that spoke volumes: Don't bring that up again.
Aizawa, who had been one of the few to maintain composure, broke his focus from the League and turned toward his students. Their expressions were full of confusion, unease, and a desire for clarity. He opened his mouth, trying to find the right way to explain things—something, anything—but paused when another voice beat him to it.
Principal Nezu had stood up from his seat.
"Excuse me, Mr. Seven," he said, politely but firmly. "Could you explain this to us? I know this is a different world and all, and you said you were going to show us a hero—but I don't understand. A hero doesn't kill people. At least, not in our world."
He folded his paws over each other, tilting his head. "I don't know if this world simply has a different definition of heroism, but I don't think you would've brought us here if that definition was too different."
His words made the room go quiet. Everyone waited for Seven's reply.
Seven stayed seated but leaned forward slightly. His tone was calm, but there was no avoiding the weight of his words.
"Well… heroes who kill are still technically heroes," he began. "But they're classified differently. We won't dive into this now, but here's what you need to understand: In this world, heroes are allowed to kill. It's not illegal. And it's not seen as something shameful by the public either."
That sentence alone hit them harder than anything else so far.
"How can that be?" someone muttered under their breath.
But before the wave of questions could erupt, Seven raised a hand and continued.
"First of all, this world works differently. The two villains you saw earlier—they weren't just villains. They were monsters."
His statement made the mood even heavier. There was a pause, awkward and uncertain, until a hand slowly went up.
It was Midoriya.
"Excuse me, Mr. Seven," he said, his voice steady but cautious. "I know the two villains were evil… but to classify them as monsters—isn't that a little—"
"No," Seven cut in sharply. "You don't get it."
He looked around the room, his voice firm now.
"I'm not calling them monsters. I'm saying they are monsters. Literally. Not metaphorically. Not morally. Physically. Real monsters—not human beings."
The shock that followed was immediate. Even those who had stayed silent so far couldn't help but widen their eyes or whisper under their breath.
"That doesn't make any sense," Aizawa finally said, brows furrowed. "That crab-like villain was talking like a person.
"Exactly," added Phantom Thief, he stood up from his seat and he earlier cleaned that he was a normal human at some point
Everyone turned to Seven, waiting for his next words.
In this world," Seven began, "there exists a unique and mysterious phenomenon… where if a certain condition is met—someone will literally transform into a monster."
The room fell silent for a heartbeat—then erupted.
"What?!"
"You mean, like… actually a monster?!"
"How's that even possible?!"
"Why isn't this happening to more people?!"
"Is it some kind of virus?"
"Does it only happen to villains?!"
Questions flew in from all directions as the students panicked and the adults sat up straighter, concern growing on their faces. Seven raised his hand quickly.
"Alright! Stop, stop right there!" he said firmly, waving them down. "Like I said—it's a mysterious phenomenon. Don't get too worked up about it. I'm not going to spoil the details for you guys."
He gave a sly glance to the screen, then muttered under his breath, just loud enough for the audience beyond the fourth wall.
"More like… I don't even know myself. Pretty sure the manga hasn't explained it fully yet."
That whisper wasn't meant for the people in the room, but it somehow echoed slightly—confusing a few sharp-eared students like Jiro, who blinked twice but said nothing.
Everyone went quiet again, now dwelling on what they'd heard. A few exchanged uneasy glances. It was Principal Nezu who broke the silence again, standing on his seat with a thoughtful hum.
"If I may," Nezu said, "what exactly triggers this… monstrous transformation? And how common is it in that world?"
Seven gave a casual shrug, then pointed toward the paused screen.
"It's actually pretty simple—and it's already been explained to you guys." He smirked. "The guy ate too many crabs. Obsessed over them. Boom—crab monster."
There was a beat of silence.
"…That's it?" someone from Class 1-B asked, eyes narrowing.
"Yeah, that's not a good explanation," muttered Kaminari. "That sounds like something Mineta would come up with."
"Hey!" Mineta yelled. "I resent that!"
Seven sighed. "Okay, okay—yeah, out of context it sounds dumb. But here's the point: obsession is the key. That guy wasn't just eating crabs—he was obsessed with them. That obsession twisted his body and mind into something inhuman."
And there are some other ways for months to exist outside of human transforming, but you will see that later
That explanation made everyone pause.
"Oh… so it's like a transformation through will or desire?" Yaoyorozu asked, trying to process it.
"Exactly," Seven nodded. "The more a person fixates on something—something irrational or extreme—the more likely they are to transform. It's not about quirks. It's about obsession. That's why it doesn't happen to everyone. Most people don't go that far."
Nezu folded his paws and nodded slowly. "I see. But even if the transformation is real… it still raises an ethical issue."
He glanced around the room, then looked directly at Seven.
"Even if someone transforms into what they perceive as a monster… that doesn't automatically give anyone the right to kill them. After all, to some people, a mutant-type quirk could look monstrous too."
Several after the audience with mutant-type quirks—like Shoji, Tokoyami, and even some in Class 1-B—tensed and spinner slightly at that.
Seven's expression turned serious.
"That's a fair point," he said, nodding respectfully. "But there's something you're not seeing yet. When a person transforms into a monster in this world… it's not just physical. It's mental. They lose who they were."
He looked back at the paused image of the crab villain's corpse.
"The guy you saw earlier was once a regular person. But when he transformed, his mind twisted. You saw it in that brief flashback. He murdered innocent people without hesitation. He enjoyed it. That's not a mutation—that's a total breakdown of humanity."
A hush fell over the room.
"Some monsters retain a bit of intelligence or personality," Seven continued. "But most… most develop one common trait."
He held up a single finger.
"They want to kill humans."
That made the message sink in.
The tension in the room began to fade as the heroes and students grasped the concept more clearly. The morality of it all still felt uneasy, but at least now it made some sense. If a creature had truly lost its humanity—if it only lived to kill—then wasn't self-defense justified?
There was no time for further debate. The episode resumed.
We see the man panting, hunched over, exhausted. Then, the voice of the well-dressed man from earlier echoed in the background:
"Has it really been three years since then…?"
The scene cut to a close-up of his eye—reflecting lights, distant and hollow. And then—
Cut.
The shot shifted suddenly to a dull, empty-looking man wearing a yellow jumpsuit with a white cape in a grocery store
It was him.
It was Saitama.
Silence fell for just a heartbeat… and then chaos erupted in the room.
"N—No way…" Bakugo muttered, wide-eyed. "HOW THE HELL—?! THAT CAN'T BE HIM!"
"THEY'RE THE SAME GUY?!" the students of Class 1-A and 1-B shouted in complete disbelief.
The realization hit like a truck. The serious, determined man in the suit who'd killed the monster with such calculated brutality… was the same bald, expressionless guy sitting on a plane like nothing mattered?
Shock rippled through the room—but no one reacted louder than Midnight and Mount Lady.
"NO WAY—HE WAS SO HOT!" they screamed in sync, grabbing their heads in disbelief.
"He had hair!"
"He had eyebrows!"
"He looked like a man with a dark past and a corporate paycheck!"
Clearly, they were not taking the transformation well.
The other heroes and students, though surprised, pieced it together faster.
"So… Saitama was that businessman all along," Aizawa muttered quietly, arms crossed as he stared at the screen. His voice carried a mix of admiration and confusion. "Truly intriguing."
There was a long pause as he processed it all. Then, almost reluctantly, he added under his breath:
"…So it's true. Even though I knew it deep down, I honestly hoped there was a chance I was wrong."
The teachers close enough to hear him turned with raised brows. Nizo sighed, realizing they'd picked up on his words. Still, he continued with quiet awe:
"Because if it is true… then in just three years, that man went from the strength level of an ordinary civilian to a level beyond even All Might."
His words struck a chord.
The room fell silent again as all the pro heroes stared at the screen, their thoughts spinning in unison.
What kind of training could do that?
They didn't say it out loud—but they all thought the same thing:
What type of quirk does he have?
Could he really have gotten this strong through sheer effort?
All Might's expression tightened. Of all the people in the room, his thoughts were perhaps the most conflicted.
"To reach that level of power in only three years…" he thought, clenching his fist under the table. "The only thing I've ever seen grant that kind of strength boost… is One For All."
He remembered his own start—the overwhelming surge of power, how it felt to control a force so vast that even walking could crack pavement.
But Saitama… he hadn't just gained strength. He'd surpassed it.
"If this guy achieved all that… could he have a power similar to one for all?"
And while All Might wrestled with the impossible, somewhere in the shadows, another man—the one known as All For One—was having eerily similar thoughts.
