Since the year 2155, Earth hasn't been known by its old name anymore. The world now calls it Neo Earth—a title that marks the beginning of a completely new era. Technology isn't just something people use anymore… it's something they live with. From the moment people wake up to the second they fall asleep, everything is connected—AI systems, neural interfaces, automated cities, even emotions being tracked and regulated by advanced tech.
Cities rise higher than ever, glowing with endless lights, powered by systems that never sleep. Transportation is instant, communication is seamless, and life—on the surface—feels almost perfect.
Almost.
Because behind all that progress… something went terribly wrong.
Humanity didn't just evolve.
It messed up.
And from that mistake… came something far worse than anything they had ever faced before.
They're called Hyonan.
No one knows exactly when the first one appeared. Some say it was right after a series of nuclear experiments went out of control. Others believe they were always there—just waiting for the right conditions to be born.
But one thing is certain:
Hyonan are not natural.
They are creatures born from radiation, mutation, and chaos. Their forms vary—some look vaguely human, others completely monstrous—but all of them share the same terrifying traits: extreme aggression, unnatural strength, and an endless hunger for destruction.
They don't think like humans.
They don't negotiate.
They don't stop.
They just kill.
Worse… they keep appearing. Again and again. No matter how many are destroyed, more take their place, like an endless wave that refuses to die out.
And their favorite targets?
Densely populated areas.
Cities filled with life.
And especially—
Academies.
Because academies are full of young people… energy… potential…
Easy prey.
At first, the world tried to fight back using conventional military forces. Advanced weapons, drones, even experimental anti-Hyonan technology.
It didn't work.
The Hyonan adapted too fast.
That's when the world realized something brutal:
To fight monsters born from evolution gone wrong…
They needed something new.
Something different.
So, nations put aside their conflicts and secretly formed a unified organization designed for one purpose only:
Eradicate the Hyonan.
That organization became known as Slashing Monster, or simply SM.
But SM didn't recruit soldiers.
They chose a different path.
They chose students.
Children with high compatibility to energy manipulation, enhanced reflexes, and mental adaptability were taken in at a young age and trained in secret. They were raised not just to survive—but to fight.
To hunt.
To kill.
All while living double lives as normal academy students.
To the outside world, SM doesn't exist.
No news reports.
No public records.
No recognition.
Just shadows doing what needs to be done.
Inside SM, every team is carefully structured to maximize efficiency in battle. Each member plays a specific role, and every role is essential.
Attacker – The core damage dealer. They fight head-on, using overwhelming power and close-range combat to tear through enemies. They're fearless… or maybe just reckless. Either way, they're always the first into battle—and the last to back down.
Caster – The brain of the team. Combining advanced tech with what feels like "magic," they manipulate energy, control the battlefield, and exploit enemy weaknesses. Without them, strategy falls apart.
Tank – The shield. Heavy armor, insane endurance, and the will to stand no matter what. They take the hits that would kill others, protecting their teammates at all costs.
Shooter – Precision from afar. Using high-tech ranged weapons powered by energy cores, they provide constant pressure, support, and long-range elimination.
Assassin – The finisher. Fast, silent, and deadly. They don't fight fair—they strike when the enemy is weakest and end things in a single, decisive move.
Five roles.
Five people.
One perfectly balanced team.
Every academy under SM operates like a hidden battlefield, always ready to deploy when a Hyonan appears.
And among all those trained fighters…
There's one name that stands out.
Reindhardt.
A student.
A fighter.
A problem.
He's been trained since childhood, just like the others—but his talent? On a completely different level. As an Attacker, his combat ability is insane. Fast, powerful, unpredictable—he's the kind of fighter that turns the tide of battle just by showing up.
Among his peers, he's considered top-tier.
An elite.
Someone you definitely want on your side.
But here's the thing…
Reindhardt doesn't care.
Not about rankings.
Not about reputation.
Not even about being called "humanity's hope."
All he wants…
Is a normal life.
Sleeping in class.
Skipping responsibilities.
Living like a regular student without missions, without danger, without pressure.
And honestly?
He tries.
He really does.
He hides his identity, acts lazy on purpose, avoids attention—anything to stay out of trouble.
But it never works.
Because no matter how much he runs from it—
Trouble always finds him.
He's tried quitting SM more times than anyone can count.
Every request?
Rejected.
Every excuse?
Ignored.
Because to them, Reindhardt isn't just another student.
He's a weapon they can't afford to lose.
"Man… there's always another mission… just give me five more minutes…" he mumbles every time his device lights up with a new call, his voice filled with pure laziness.
But deep down…
He knows.
No matter how much he complains…
No matter how much he wants to rest…
When the time comes—
He'll still stand up.
Because in a world that's constantly on the edge of destruction…
People like him don't get to choose.
And fate?
Yeah…
Fate doesn't wait.
