Ten years ago... the world—Earth—was conquered by monsters from another dimension. Seventy percent of the human population vanished. Humanity teetered on the edge of extinction.
Then, hope arrived from an unexpected place: heroes from another world. Their leader told us that their dimension had suffered the same fate. They had lost their planet to these very monsters. Through countless sacrifices, they had managed to defeat the creatures... all but one. The strongest of them all. The source. The devil.
Confident and desperate, the heroes challenged the devil. One by one, they fell—until only one remained: Daniel, the most powerful among them.
Daniel fought the devil in a battle that shook the heavens... and in the end, both perished. Or so we believed.
Though the devil was slain, he left behind remnants—creatures not as powerful as he, but still deadly. Monsters now roam Earth, ranked from F to SSS. On the Daniel Scale, they range from Level 1 to Level 15.
But Daniel didn't just die. Before his final breath, he scattered fragments of his power across the globe, choosing worthy individuals to inherit it. These chosen ones became known as Hunters—warriors who defend humanity from the devil's remnants.
They say Daniel's home world is now a graveyard. That his people entrusted him with their combined strength—an energy capable of defeating even the devil himself.
Still, some say Daniel made a fatal error. He missed something. The devil left behind more than monsters—he left behind a secret.
A rumor whispers of a pill... a strange, disguised object Daniel left behind. Said to contain the essence of his full power—not just his, but the power of his entire world. Enough to destroy the universe itself. Scientists are obsessed with it. The world's greed needs it. But no one has found it.
It's just a rumor... right?
Ten years have passed.
Now, Hunters are Earth's greatest heroes—and its highest-paid. Even a Rank F earns a million dollars per job. Risky? Absolutely. But after the downfall of the old world, what's left to lose?
Skills aren't given. They're earned. Passed down by the chosen, or learned through training. True power, however, comes from the original skill holders—those who inherited Daniel's abilities directly. They are now legends. Professors. The elite.
Hunter schools and guilds exist all over the world. And while copied skills can hold their own, original skills remain the strongest weapons against the darkness.
The world still searches for Daniel's hidden pill... but no one knows where it is.
Until now.
