Inscription Talisman

The word doomsday is unfamiliar to many people. But for humans in 3781, this is synonymous with this world. Unknown creatures have invaded Blue Star.

They possess powerful physiques, and the order of power from low to high is: ghosts, ghosts, and demons. I'm a newbie writing a book, so please forgive me if it's not good.
