Sky Demon Domain.
The sky, a blood red expanse.
Above the sky, with neither sun nor stars in sight, only bizarre lightning flashed, one bolt after another.
On the dark brown earth, not a blade of grass grew, and the air was suffused with an unsettling intent to kill and the odor of death.
A heavy, filthy mist pervaded everywhere, turning even the air dark.
Rain poured down in torrents, yet the rain itself was red as if crying, as if bleeding...
In this world, there seemed to be only the colors of blood and black.
Though it was called the "Sky Demon Domain," in reality, it was just a comparatively larger Restricted Area.
Secret Realms and Restricted Areas were, in the end, merely fissures where worlds connected.
For millions of years, the Sky Demon Race had been chased here by the Human Race, unable to escape.
Time and again, they attacked the Seal, infiltrating The Heavenly Feather Realm...
And time and again, they returned defeated.
