I was Thrown into an Unfamiliar Manga

Sakagami Maou couldn’t believe his eyes.
“What is this?! What the hell is this?! What the hell is going on?!”
Just for today, he’d believed with 99% certainty that he could bury Goto Kazuya for good.

But just like always, at the last moment, that guy performed a miracle.
He pushed through that 1% chance.
And the one who had brought about that miracle was the man Goto called hyung-nim.

A head or two taller than the average person, with an overwhelming physique that looked like a mass of muscle even through clothing.
He had the monstrous strength to hurl people effortlessly, the durability to remain unflinching against most impacts, and the courage to stand his ground even when facing dozens of enemies.
It was as if he had been born solely to fight.

One could not help but wonder—was that man truly the same species as himself?
“Aaaaaaagh!”
Another mohawk let out a scream and was sent flying after being struck by the man’s bokken.

He had already been strong barehanded, but now that he wielded a bokken, he was even stronger.
Every time he swung the bokken with both hands, the subordinates flinched and scattered left and right.
The bokken produced such an oppressive sound that it could be felt even from afar.

Each swing sent a person flying—an utterly surreal sight.
“Tch! Bunch of idiots!”
Watching the situation unfold, Maou finally decided to step in himself.

“Out of the way!”
BUAAAAANG!
Revving the engine of his signature red bike, he charged at the man at blazing speed.
He looked like a raging bull.

“Dieeeeee!”
He shouted with madness in his eyes and lowered his body in preparation for the impact—
Thud!

Astonishingly, the man wasn’t launched like a cannonball.
Instead, he threw aside the bokken he’d been holding and braced himself, grabbing the 500cc bike’s front bumper with both hands and holding his ground.
An absolutely ridiculous sight.

“You idiot!”
Stunned, Maou stepped harder on the accelerator.
The RPM gauge on the dash began climbing endlessly.

The man’s pillar-like body began to be pushed back little by little—but then he rendered Maou’s final desperate effort meaningless in an entirely different way.
He lifted the entire bike and Maou on it—well over 200 kilograms—straight off the ground.
Then he slammed the bike into the ground.

With the shock of the impact, Maou was launched out of the seat like a ball.
If he hadn’t been wearing full-body protective gear, he might’ve sustained serious injury.
As Sakagami Maou lay sprawled on the ground beside his beloved motorcycle, the man slowly approached him.

The shadow of the hoodie concealed his face, which only amplified the fear.
“A-a-a monster…!”
But the man muttered in disgust,

“Who are you calling a monster?”
The last thing Maou saw before losing consciousness—
Was the muddy sole of the man’s shoe.

SMASH!!
***
With the unconscious Maou slung ~Nоvеl𝕚ght~ over my shoulder, I forcefully removed his red helmet, now dented from the impact.

So that’s why he never took it off—his face had a large burn scar.
Was it a complex or something?
Anyway, once the mohawks realized their leader had fallen, the ones who had been fighting desperately began dropping their weapons one by one.

I picked up the bokken I’d been using to control my strength and approached Goto, who seemed to be catching his breath now that the fight had cooled down.
“The bokken came in handy.”
“Ah, yes.”

I laid the man called Maou down on the ground and asked,
“So, what now?”
“…I have to set things right. If I really want to retire properly.”

“Do what you have to.”
I said that, then gave Goto a pat on his bloodied shoulder.
“We broke the promise we made between us, but the gym’s always open. Come train anytime. The director really likes you.”

Looking at me with a blank face for a second, Goto soon smiled in relief.
“Yes, hyung-nim!”

Later, after everything was resolved and Goto came back to the gym, he told me the rest of the story.
In the end, both Hyakki Yagyō and the Devil Riders—two major biker gangs—were destroyed together.
Hyakki Yagyō crumbled due to internal conflict from the betrayal of trusted members, while Devil Riders dissolved naturally after their boss Maou disappeared in disgrace following his overwhelming defeat, leaving no successor.

The team Goto had tried so hard to protect vanished into history—but Goto spoke with a surprisingly peaceful expression.
“It’s probably for the best. I’d already decided to leave Hyakki Yagyō anyway. The group’s purpose had started to change.”
“The purpose?”

“Originally, Hyakki Yagyō was just a small club made by people who wanted to ride. The first boss, Mishima-senpai, was cool and stylish—someone everyone looked up to. The second boss made bold claims about turning us into Tokyo’s top biker team, carrying on Mishima’s legacy. I was the same—I charged ahead with that same goal. But it wasn’t supposed to be like that. As our numbers grew too quickly, more people started trying to take advantage of us.”
A familiar story.
Rapid growth always came with side effects.

“Honestly, I never thought Mito would betray me. We joined Hyakki Yagyō at the same time. He wasn’t like that back then. I don’t know what happened…”
“Well, you can’t cut everyone slack. Even if you’ve known someone for years, if they stab you in the back, they’re the one in the wrong.”
If he hadn’t betrayed you now, he would’ve done it later anyway.

“Maybe you’re right.”
As Goto sat there with his face still clouded in worry and sorrow, I shrugged.
“Either way, you’ve retired now. That means you need to cut ties with that world completely. You don’t want to keep getting dragged into messes like this, right?”

“…That’s true.”
“You’ve been reborn, Goto. From now on, the thing that’ll walk beside you in life isn’t a bike anymore.”
I handed him a 10kg dumbbell.

“It’s this dumbbell.”
“Hyung-nim…”
“So stop wasting time worrying. Do one more dumbbell curl instead.”

I stood up as I said that.
My five-minute break was over—it was time to get back to training.
Goto, holding the dumbbell in his right hand, stood up too and shouted in a voice full of emotion,

“Hyung-nim! I’ll follow you for life!”
“Keep it down in the gym.”
“Ah, yessir.”

And so, Director Nakayama’s fitness club gained a new member.

[Is this really how high schoolers fight these days lololol]
A video uploaded to an online platform under an anonymous ID quickly spread among Tokyo’s high schoolers.
Filmed with a shaky phone camera of unclear origin, the footage began in darkness.

As lights turned on from all directions, dozens of motorcycles were shown facing off in what looked like a construction site—it was clearly a biker gang standoff.
Though biker gangs had died out since their 90s heyday, there were still those chasing the nostalgia of that era. These self-styled “riders” gathered under a new name.
And in this video, the two largest forces among them clashed: Setagaya’s Hyakki Yagyō and Meguro’s Devil Riders.

In the opening, a man with a regent hairstyle in a black special uniform arrived on a motorcycle, and a man wearing a red bull helmet—presumably the Devil Riders’ leader—spoke to him provocatively.
The audio was terrible, so the dialogue couldn’t be made out, but the tension and gestures made it clear that a fight was about to break out.
And then the two gangs clashed.

Despite being severely outnumbered, the regent-haired man fought like a demon with his bokken.
But eventually, as one after another of his allies fell, Hyakki Yagyō’s members were pushed into a corner. Just as the beating was about to become one-sided—
‘That man’ appeared.

With his face hidden deep under a khaki hood, the man’s massive frame and overwhelming muscles radiated such power that it could be felt even through the low resolution.
He arrived late, and single-handedly demolished the Devil Riders.
Even with the awful video quality, his unbelievable combat prowess was vivid.

The 15-minute video ended with the helmeted enemy leader collapsing unconscious beneath the man’s muddy boot.
The clip stirred controversy online about its authenticity, but nothing concrete was ever uncovered.
There was only one thing everyone unanimously agreed on—

The man in the video was now known by a single nickname:
“Tokyo’s Strongest.”
