The world was ordinary... until the Gates appeared.
They weren’t earthquakes or meteors—no, they were cracks in reality itself. Glowing circles of energy, opening in city skies, deep forests, and beneath the oceans... and from them came the monsters.
At first, the armies fell. Then, the nations.
Humanity stood powerless.
But then—almost as if some unknown force sought to restore balance—certain people began to change. They woke up with strange abilities. Powers no science could explain.
The world called them:
> “Hunters.”
Men and women who braved the Gates, fought monsters, and returned—if they were lucky.
But not all Hunters were equal. Their ranks varied wildly—from the feeble Rank E... to Rank S, capable of leveling mountains with a single strike.
In this chaos, Guilds emerged. Powerful alliances of Hunters that rivaled governments, controlling entire cities, competing for the treasures hidden deep within the Gates.
But that wasn't the end of it.
Over the years, rare cases began to surface—Hunters who touched something older than the Gates. Deeper than power.
Something unseen... a Pact.
And soon, whispers spread among the strongest:
> Those who form a “Pact”... are no longer mere Hunters.
Very few know what it takes. Fewer still understand the cost.
And here... is where our story begins.
The story of Kaido Shin, an E-rank Hunter.
A boy with nothing—except love for his sister and a heart that refuses to break.
One day, he stepped into a Gate... and came out someone else.
Someone bound by blood.
