After a tumultuous court uprising, Princess Kalista found herself being pursued. A valiant knight risked his life to shield her from the dangers, ultimately perishing before her very eyes. In her dying moments, through a twist of dark sorcery, Kalista was transported five centuries after into the future where she emerged as a lowly handmaiden within the walls of a familiar castle. Deep within the dungeon, Kalista encountered the knight's visage once more, yet he bore the horns and tail of a devil, clearly not the man she once knew.
