Dane Harper's life was a monotonous grind. Stuck in a soul-sucking 9-to-9 job with barely any time to breathe, his only escape was the world of visual novels. From anime to manga, light novels to webnovels, Dane had consumed it all, but nothing compared to his ultimate obsession: Harem, Dragons, and Deities (HDXD).
This legendary visual novel was a masterpiece of high fantasy, packed with detailed lore, jaw-dropping twists, and, of course, an insane harem of monster girls and powerful women.
Dane had spent nearly 7,000 hours playing it, chasing every ending possible, especially the legendary [Overlord of Humanity Ending], where the protagonist builds a massive harem and spreads his superior genes across the HDXD universe.
But when a cosmic accident caused by a mischievous witch-in-training, Beatrice, wipes out the entire human universe, Dane's life takes an unexpected turn.
As the first soul to be reincarnated, Dane is offered two wishes by Beatrice: a world of his choosing and a fragment of her power. Without hesitation, Dane chooses the world of HDXD, a place he knows inside and out, and a unique ability to help him survive: the Omni Harem System. This system not only helps him level up and gain unique powers but also guides him in building the ultimate harem.
Now, reborn as some random extra of this hellish game, Dane is ready to live out his wildest fantasies. His life goal, walk over the MC, and replace him... But this isn't just a game anymore; it's real life, and the stakes are higher than ever.
From battling dragons and deities to navigating the complex personalities of the women around him, Dane must use his knowledge of HDXD and his new powers to carve out his destiny without getting curve stomp by the overpowered people around him.
But let's be real, becoming the Overlord of Humanity isn’t going to be a walk in the park. This is HDXD we’re talking about; a world where one wrong move can lead to a bad ending so messed up it'll haunt your dreams.
As such, every step towards that ending requires heart, commitment, and sheer will, and you best believe Dane is aiming for that ending at all costs.

Shameless Author Reviewing himself, because he really enjoys writing his novel. MC is stuck as an 5-year-old in game. It's different. When writing he can't decide what to call the game world so he left it blank. It was kind of his own stupid joke to just call it blank.0 0 Reply

Splendid novel characterized by inspiring characters and grimly appealing worldbuilding. The central concept is as chilling as can be. Apart from human bravery, this world is a desolate and frightening place that is terrorized by beings beyond imagination. The style is very much characteristic to the author, concise, clean, and impactful. Another thing that pops out is the intensely likable main character. Plot is tense. Very tense. Never seen such a colorful combination of post-apocalyptic and wildly dreamlike stuff before wrapped in compact and witty words like this, but I sure do love it.0 0 Reply
