Six Rivers Of the Netherworld

Just outside Raizel's window, two figures stood calmly in the air. The first person was a tall figure with delicate features and a black, silk blindfold around his eyes. He held a silver cane and stood with a gentle smile.

The second person had short blond hair with black pupils. He wore a long black and white rob.

He chuckled and stretched out his hand and a book appeared before 

The cover of the book was extremely odd. It was like paper yet not paper, like iron yet not iron, like jade yet not jade, and completely pitch black to the extreme.

However, even in the darkness of the book, everyone but the mundane or cultivator, human or ghost could see the words written clearly.

'Book of Life and Death.'
