Meikyu Wakusei des Paraiso

Long time ago, the universe far away ....
The human race that diffused into the sea of stars built many huge empires in its territory and destroyed them.
And so many years passed by that it was not enough for both hands to pass out, and the species left by mankind, though feeble, were nurtured by stars, and reached out again to the vast sea ― the beginning of the Galactic Age.
Many planets were rediscovered, and various legends were created and told by lost technologies.
And here, Paraiso, the planet of the sea of clouds, is one of the places where the mysterious legend sleeps.
the blasphemous sacrament of eternal immortality created by the emperor of Avalitya, one of the old seven galactic empires. Many people still die today seeking the hidden treasure and honor that is said to be hidden deep in the planet Paraiso. The maze of death and the planet of clouds, which engulfed an enormous number of lives, were called the Meikyu Wakusei des Paraiso, implying that it was heaven.
