The Road to Salvation! Begin!

When the lights of the sun, moon, and stars converge, the Key of Light that will save the world shall descend here.

The girl who fell from the sky said this to the boy, her smile as bright as a flower.

People called the girl the world's most despairing darkness.

When the Key of Light that will save the world touches the Gate of Darkness that will destroy it, the true face of this world will be revealed.
