“When your gacha waifues are real but so are the monsters.”Leon had finally made it. After nearly a decade of surviving off instant noodles and blind faith in himself, he created the most chaotic, soul-crushing, and waifu-filled gacha game the world had ever seen. Then he sold it, bought a Bugatti, and hit the road to touch grass like any gamer should.Of course, the universe didn’t let that slide. How can a Gamer touch grass?One glowing portal. One crash. One very unexpected reincarnation later—he wakes up in his own game world.A world crawling with mutated, Abyssal beasts, corrupted cities, and a virus that’s slowly wiping out the population, especially males.A world where men are protected assets, female-led militaries run everything, and of course, there is also another world that is fully Corrupted connected to his new world.Now bound to a mysterious SSS-Rank Dungeon that activates when he sleeps, Leon has one goal: survive and become stronger.Which is easier said than done when every death comes with boosted pain, his system is still syncing, and half the girls he designed could probably bench-press a tank.But hey—at least they’re hot and lovable. That's what matters in the end anyways.....Just a heads up.This novel will be an amalgamation of everything with action, adventure, waifues, gacha game world building and all, comedy, harem, character interactions, emotional moments, desparation moments cuz it's apocalyptic world bruh. A good lore and all too.Smut will be less as I want to focus more on their character development and interaction in the harem rather than just sex.
