At first, it was just a normal morning.
People walked to work. Kids went to school. The world moved like always.
Then, the sky cracked.
Not in a way people could see with their eyes. But something broke—a rule, a barrier, a wall that was never meant to fall.
It began with the screams.
In the middle of Tokyo, a hole opened in the air. A swirling black gate, floating above the street like a nightmare. The sky around it turned purple. Lightning sparked. Time felt slower near it, like the world was holding its breath.
Then something stepped out.
Its skin was gray and wet. Its eyes were red and empty. Its body looked half-human, half-worm. It moved like it was in pain. But when it opened its mouth, it laughed.
And then it started killing.
People ran. Police fired their guns. Nothing worked. Its claws tore through flesh. Its tongue stretched out like a snake and dragged victims into its stomach.
More monsters followed. Big ones. Small ones. Flying ones. Crawling ones.
Each came from a different gate. Each came from a different nightmare.
Humanity called them Dungeons—portals to another world. A world filled with monsters, death, and power.
And from the bodies of those monsters came Skills. People who survived fights with them sometimes awakened strange abilities. Super speed. Magic fire. Healing hands. Strength beyond belief.
They were called Awakened.
Heroes were born.
But so were monsters in human skin.
Some people used their powers to help.
Some used them to kill and take more.
And somewhere far from the city—inside a dark apartment—a lonely, broken boy stared at a cracked mirror.
He didn't know it yet.
But he was going to become the most dangerous kind of monster.
The kind that pretends to be a hero.
