Two millennia ago, humans developed spyrix, a power source which absorbs spirits to supply power. In response, the spirit Maxwell gathered humans, who share a symbiotic relationship with spirits, onto an isolated land protected by a barrier; the isolated land became known as Rieze Maxia and the outer lands as Elympios. As spirits are needed to sustain nature, Maxwell waits for the day all humans on Elympios die off before dispelling the barrier. Twenty years prior to the present, an Elympion cruise ship becomes trapped in Rieze Maxia, eventually forming a terrorist group known as Exodus. Exodus works with the Elympios military to find a way to destroy the barrier. In the present era, Rieze Maxia is ruled by two countries called Rashugal and Auj Oule. While the two countries appear to live in harmony, they both initiate black operations in attempts to conquer the other in hopes of uniting Rieze Maxia as a single country. In the present, medical student Jude Mathis investigates a military research facility in order to search for his missing professor. There he witnesses a spyrix-powered weapon called the Lance of Kresnik absorb his professor. The military prep Jude as the next victim, but he is saved by Milla Maxwell, Maxwell's successor.
