A world consists of two planes of existence. There is the world of the living, where humans, elves, and every whole-spirited creature breathe. Then there is the Void, where demons and beings made of pure darkness, shadows, live.
Almost fifteen years ago, these shadows brought the deaths of the Kingdom of Sylenia’s beloved king and queen and the disappearance of their newborn baby. In the present day, the kingdom remains in the capable hands of a young queen, her major generals, and their knights but is constantly threatened by the growing number of shadows that enter the living world.
A secluded young orphan named Kanna is one of the new apprentices that have been chosen to be trained for the purpose of defeating these shadows. Suddenly called upon to become a knight’s understudy, she is escorted to the palace by two older apprentices. Along the way, she is attacked by the shadows, much to the apprentices’, knights’, and even the major generals’ confusion.
While Kanna is figuring out why the shadows are targeting her, something else occupies her mind. Every time she is knocked unconscious by a shadow, she has familiar visions about a little boy she vaguely recognizes. Kanna eventually finds the boy that keeps appearing in her dreams. However, she meets him as a price due to the presence of a darker, more powerful entity: the Dark Irregular.
