Possessed by the Ghost King from the Start

Because of the spirit-summoning arts practiced by the older generation, some of the evil spirits they summon are too powerful to be "sent back." They possess people and cause harm, and many things science can't explain stem from this.

Some people fear birth, aging, sickness, and death.

They crave money, power, beauty, and pleasure.

To overcome their fears and satisfy their desires, they inherit or devote themselves to studying all kinds of dark arts, such as "spirit summoning," "black magic," and "life extension."

As for me, I've been possessed by a ghost known thousands of years ago as the King of Ghosts, and we fight side by side!

You say your summoned ghosts and dark arts are powerful?

Come on, let me show you what a true ancestor can do!
