The sky is black and grim. Blood is smeared all over the streets like graffiti. There - a demon's shadow. It hollers as it snaps a peasant's body into two. But nineteen-year-old Kahri Sahar was dealt with the worst cards; the demons have cursed beloved brother into nothing more than a decaying ragdoll. Now, equipped with nothing but a bloody butcher knife, Kahri must face those demons to find the legendary fruit that may save her brother's life. While the desert town Kahri lives in is menacing enough, the unknown world she must traverse is perilous. With bloodthirsty demons at her heels, Kahri must learn to trust the Demon Lord's right hand, Micah von Schwarzergeist, to even have a sliver of a fighting chance. Whether or not Micah's intentions are pure, Kahri is left with no choice but to enter a cold, bloody battle of morals, betrayal, and magic - just to see her brother smile again.

In the year XXXX, the Earth was born anew. The ethereal being, Gaia, descended upon the planet, and gave mankind a gift- a gift of unimaginable power. Thus, the Adepts were born- individuals who held mysterious and unique abilities, called Curios. These powers threw the Earth into chaos, with many unable to control their newfound abilities. From this darkness rose a group of skilled Adepts who used their Curios for good, and brought peace across the land, establishing order and rule to the broken planet. The Earth still needs heroes like these. The Earth needs Aces, who can protect the world from those who abuse their powers. April knows this. But she's a Null. She has no Curio. She's useless. But when the Adepts around her fail, what is she willing to do to protect the ones she loves?
