A DEMON WITHIN. AN UNKNOWN ENEMY. A DEADLY THREAT. Gothalia Ignatius-Valdis is cursed and hated, but will be her home's greatest asset. In the underground country of the Fire Reserve, New Icarus is home to the Excelians with superhuman strength, speed and elemental powers. Long ago, these beings were once Human but due to a suppressed gene that every Human carried, they awakened before being hunted for their exceptional abilities. Centuries passed since those dark times, and the Excelians now live peacefully in the City of New Icarus, harnessing the power of their élanocytes. Though, Gothalia had the ill fortunate of being born with a high level of unstable élanocytes inherited from the Valdis clan. As such, she's always been an outcast, from the day she was born, often called a "demon". Suddenly, at the command of the Grand Elders, she's forced to enlist into the military and not just any military--the Centurion division where she meets Danteus who becomes her most unlikely companion. The Centurions are the Fire Reserve's first and last line of defence making their life is expectancy much lower than the average Excelian. So when peace of their home is threatened, Gothalia will be forced to act. Though, the question remains, will she aid them after everything they've done?
