In this world, once every thousand years, the Demon God and the Hero meet on the battlefield and fight to the death.
No two battles ever end the same way. Sometimes the Hero stands victorious. Sometimes the Demon God wipes everything away. But no matter the outcome, one thing never changes—the sheer, overwhelming surge of magic they unleash.
It's too much for the world to contain. That excess power has nowhere to settle so it spills out, drifting into the endless void beyond the sky, wandering through space for thousands of years.
And then, one time, something went wrong. The clash was too violent. The magic tore through space itself, ripping open a crack and creating a wormhole, and that wandering energy was pulled through it.
On the other side was a blue planet called Earth.
By the time the magic reached it, the power had already thinned out, worn down from its endless journey. It wasn't strong enough to shatter continents or burn the sky apart. But even in that weakened state, if it struck living beings directly, it would still be more than enough to erase countless lives in an instant.
The energy fell straight toward the ocean. But that day, the ocean wasn't empty. A ship drifted across its surface, carrying a group of high school students and their teachers on a trip. Laughter had filled the air not long before. Voices overlapped, light and careless.
No one noticed the sky change. No one saw the moment the energy broke through. It struck the ocean without warning.
Water exploded upward in a violent surge, rising so high it brushed the clouds themselves. The sea roared, twisting and folding in on itself and the ship, caught at the center of it all, was swallowed whole.
There wasn't even time to scream. No one understood what had happened. In a single instant, it was over.
Every life aboard the ship disappeared before a single thought could form. And it should have ended there.
But it didn't.
The magic carried something with it, a lingering trace. As the energy scattered, it pulled at the souls of the dead, dragging them along the same path it had taken.
Back through the tear in space. Back to the world it came from. The souls didn't stay together. They scattered, drifting across the land, each one pulled toward a different place.
One by one, they found new vessels and new lives.
This story is about one of those souls.
