Bone Pattern Book

There are lines on the bones, and the world is hidden in the spine. Seven lives of reincarnation, a mystery of nine seals. The last son of a family who was reborn with incomplete memories, carrying the secret of the nine bone seals on his spine, searched for a path that belonged to no one in the thousand-year chess game of the nine major families. But as he gets closer to the truth, he discovers that the "self" who wrote the warnings in the previous six lives is leading the next life into a deeper trap with every step. And sleeping deep in the eighth vertebrae is another identity that he doesn't even know about. The three prongs are on his back. If the direction is reversed, everything will go wrong.
