In a world where dungeons randomly appeared in cities, hunters became the new celebrities—
their faces on billboards, their battles streamed live, and their ranks that deciding their place.
But among them, there was someone even stronger than all ranked hunters combined.
Her name was Yumi Kurogane.
A beautiful girl with long black hair, glowing crimson eyes, and strength so overwhelming that even the most dangerous SSS-class monsters died with a flick of her finger.
Yet… no one knew who she was.
Because Yumi never registered as a hunter.
She never wanted fame. Never wanted interviews. Never wanted to be dragged into politics of guilds and governments.
She only wanted to live a quiet life, eat good food, and grind her levels in peace.
Yes—
while the world struggled with monsters…
Yumi alone possessed the Leveling System.
A gift no one else had.
A system that grew with her to limitless heights.

Today, in Tokyo — Dungeon Outbreak #772
"Boss, we're losing men! The Frost Tyrant is too strong!"
"Where the hell is the Top 1 Hunter, Kael?! We need him!"
The S-Rank raid team was being pushed into a corner. Ice spikes erupting everywhere, their tank's shield shattered, their mages collapsing from exhaustion.
The monster roared, releasing a freezing shockwave that sent trained hunters flying like insects.
And in the middle of the battlefield—
A girl in a hoodie quietly sipped bubble tea.
Yumi looked at the collapsing hunters with a sigh.
"So noisy… I just wanted to buy snacks."
She placed her drink down and stood up.
No one noticed her.
No one ever did.
She walked past the panicking hunters, her eyes glowing faintly red as the system window appeared.

**[ Level 231 ]
[ Skill: Absolute Strike – Ready ]**
---
The Frost Tyrant roared at her—
then stopped.
As if realizing it was facing something far beyond its league.
Yumi stretched lazily.
"One hit."
She swung her hand downward like swatting dust.
A silent flash.
A shockwave that split area around.
The Frost Tyrant—
an SSS-class boss—
died instantly, reduced to ice particles.
The entire raid party froze in shock.
"What… what just happened?"
"The boss… disappeared?"
"Was it Kael? Did he snipe it from a far?"
"No… I didn't even sense mana…"
Yumi picked up her bubble tea and slipped away while everyone panicked.
Another day.
Another dungeon saved without anyone knowing.
---
Outside the Dungeon
As she left, a news broadcast played on a nearby screen.
> BREAKING: Kael Once Again Defeats an SSS-Class Dungeon Alone! Declared World's Strongest Hunter!
Yumi sipped her drink.
"Eh? When did he do that? I clearly killed it though…"
But she didn't care.
Rankings, fame, glory—
none of that mattered.
As long as she could keep leveling in secret, she was happy.
And so, the strongest hunter in the world…
remained unknown.
A hidden shadow.
A silent protector.
A girl who could erase the strongest monsters with a single casual strike.
Her name—
Yumi.
And someday, the world would learn her true power.
But not yet.
Not today.
Today…
she just wanted more bubble tea.
