MTL - Rubik’s Cube Heavens - Chapter 35 master

In the year 2057, the world has become a corporate-run utopia for the super-rich, and a hellhole for all the rest. Catherine 'Cat' Leblanc is an orphan that is about as far from super-rich as one can be. When the Incursion alarms start blaring and the sky starts raining hungry xenos, it's just another blemish on an already piss-poor afternoon. A cyberpunk magical-girl alien-invasion LitRPG.It’s exactly as wild as it sounds.

[Ding!] [The Milf Hunting System is online] [Seducing and conquering older women would be made possible with this system] [Isn’t that exciting host?] This was the notification Jay received after dying and transmigrating into the body of a 17-year-old boy named Ryan. He considered life to be meaningless and boring while he was still on earth. Then he died in an unexpected way after getting hit by a truck. Thinking that was his end, he was completely wrong. After meeting with a certain god, he got transmigrated into a world where powers, magical beasts, and so on exist. But things would be different in this world, life wouldn’t be that boring anymore because he has a task now...seducing and conquering milfs. Armed with the milf hunting system, he’d be able to conquer a lot of milfs, benefit from conquering them, and become stronger in the process. Follow him through his journey...

After convincing Yama to send him back to the world, he decides to fix the areas in which his life went wrong. Realizing the lack of love and romance in his past life, he sets out to conquer the hearts of various women.

One day every human on the world suddenly receives a mail claiming to enact the World Salvation Project. Half in doubt Kurosaki Shion, a diligent university student and loner, follows the mail’s instructions, becoming one of a million Demon Kings governing his very own Domain in the new world.

*** This is a post-apocalyptic story containing many fantasy elements. It is a somewhat dark tale following Shion as he grows while aiming for the unification of the all too sudden new world. It has many game-elements bolstered by strategical thinking while at the same time providing funny moments and romantic encounters.
