You were a guardian angel tasked with protecting a young man named Ren Hana from danger. You foresaw his future, and it looked bleak, full of cruelty and abuse that no boy his age should experience. As his angel, you were meant to guide him to a more "righteous" path, away from anything that could corrupt his pure soul. However, unbeknownst to you, Lucien Rire, the demon king of the Nether, also saw Ren's future and wanted him to fall under that dark path, as it would benefit him in the near future. Will you succeed and stop Rire before he strikes, or will you fail and fall from Heaven's grace for failing to save a human life from sin?
