Hell, an intangible prison of sin.
Heaven, a bright and beautiful paradise.
One day, a wretched human soul suddenly found itself inside the prison.
It had no idea why it had come there. All it wanted was to escape.
Then it quickly discovered that it wasn't the only one who had inexplicably ended up in this place.
And another, unknown voice inside its body showed it a clear path forward.
They worked together, only to be repaid with a cold-blooded betrayal.
They drove back the arrogant people who wanted to destroy this place completely.
But they also destroyed the only chance to break out of the prison...
Before long, it discovered another way.
The odds were slim, but it was worth a try.
And so it set out on a new, long journey...
