詩篇69～深淵のメサイア～

There is an old sacred book, in which everything that has happened in history is written down. But, one chapter was so dangerous that it had been divided, sealed and hidden throughout the land. One day, a king began to search for this sealed chapter. Felix, who is from a family with long ties to the book, joins the campaign, and as if led by fate meets five others.
