Literary Edition
A notebook said to be cursed, a demon said to be sealed in the book, a truth said to be unknown to anyone. It has gone through countless lives, spanned tens of millions of years, and changed many masters. Can this notebook be placed under the bright sun? Can this demon get his redemption? Should this truth be made public, or will it continue to be submerged in the long river of memory?
