Nether World Sector

The Nether World Sector is a world that belongs to the deceased. Most of the residents of the world are ghosts. It seems that a destructive super war once broke out in their world. The parties involved in the war all resorted to the calamitic magical equipment. The fatal mystic rays swept across the surface of the entire planet. Not only were most people killed at once, they were also transformed into ghosts. It is a world of the angry wraths and apparitions. Although they had already become ghosts, they never let go of their hatred for each other, continuing to fight as ghosts.
