The tower of the gods overlooks two great kingdoms.
In that tower lives one girl...
Before her a young man named Lucius appears.

She takes his hand and he shows her the outside world.

On the way, to the capital they help a mysterious young man who was dying in the streets and together they proceed...

While over time, her feelings grow stronger...
The day of their parting draws near...

She learns of love... and at the horizon of love and hate...
The truth of the world, of existence... becomes clear---
