After a young man's untimely death he awakens in hell, unable to recall anything about himself. Rescued by a powerful free-soul, he is thrust into a war of epic proportions between the few surviving free-souls, and an endless onslaught of demons, all the while trying to piece together his past life. With every free-soul suffering from the cursed amnesia, he is forced to traverse across the entire plane to find answers. What he finds, however, may shatter the very foundations of hell itself.
