HDXD: Omni Harem System Novel

Dane Harper, a burnt-out office worker whose only escape was visual novels, had one obsession: Harem, Dragons, and Deities (HDXD). After spending 7,000 hours mastering every route in this fantasy game, particularly the "Overlord of Humanity Ending" where the protagonist builds a massive harem, Dane's mundane existence ends abruptly when a witch-in-training named Beatrice accidentally destroys the human universe. As the first soul to be reincarnated, Dane receives two wishes: a world of his choice and a fragment of Beatrice's power. He chooses the HDXD world he knows intimately and receives the Omni Harem System, granting him unique abilities to level up and build his ultimate harem. Reborn as a random extra in this now-real world, Dane aims to overthrow the original protagonist and achieve the Overlord of Humanity ending. However, surviving among dragons, deities, and overpowered beings while navigating dangerous routes requires unwavering determination—one misstep could lead to a catastrophic bad ending.
