Hundreds of years before Lenneth's tale, another saga lies concealed by the gods. The valkyrie Silmeria once served Odin loyally, but after an incident ignited a conflict between them, Odin forcefully reincarnated her as a human. The human soul that would carry her spirit was that of Alicia, Princess of Dipan. The forced transmigration causes Silmeria’s spirit to awaken within Alicia, leaving two souls to inhabit a single body. The spirit that should have been sealed has awakened—a situation Odin will not ignore for long.

The prequel to Valkyrie Profile, this installment introduces the new Photon Action System to the classic side-scrolling action format. Projecting photons grants players more freedom to explore and expands the action. Add to that "sealstones" that affect the laws of nature in dungeons, launching strategy to new heights.
