When the World falls into darkness, and Demons roam free, the Angels shall descend and banish the dark, and seal away all the Evils of the World. The Seraph of the End will erase the past, and bring about a new, untainted World. The prophecy has foretold so... but even the Seraphs must be cautious if they wish to challenge the Will of the Supreme Beings. (This is a rewrite of Archdevil's Descent)
