—The battlefield of ten years ago—
The wind was cold.
The scent of iron piercing the nostrils. The smell of blood mixed with soil. The sound of explosions and shouting echoing in the distance.
Gintoki slowly opened his eyes.
It wasn't a familiar ceiling—it was the sky. Black smoke was rising from beyond the cloudy heavens.
The sensation of the cold ground pressed against his back. As he sat up, he found himself on a hill with a panoramic view of the surroundings.
...What is this place?
Gintoki furrows his brow.
As if responding to that voice, a call came from a short distance away.
