Sin System: Demonic Harem After Reincarnation

Zarek Voss was executed for a crime he didn’t commit—framed by the elites, erased like trash. But death didn’t end him. He awakens inside the System Nexus, a god-level terminal only legends speak of. A voice welcomes him: “Welcome, Glitch Protocol Activated. All limits removed.” Now reborn in a brutal world ruled by System-born tyrants, Zarek isn't a player in the game. He’s the God rewriting it. With the Godroot Core, he can steal skills, reroute power, erase bloodlines, and even crash the entire system’s rules. He’s hunted by factions, feared by immortals, and followed by rebels who whisper: “He’s not chosen. He’s the error that will end it all.” Zarek will not just level up— He will ascend. Or destroy the System trying.

Superpowers abound. Villains rule the world. A transmigrated dork that has absolutely no idea what’s going on. Strong-armed by the Superhero Enhancement System into the thankless job of endlessly performing good deeds in a world where such actions are often met with violence, Lucas Lynn doesn't have much choice in regards to using his supposed gifts. It’s bad enough having to pretend to be a supervillain, but how exactly does Boss System expect him to save the world with only the help of a homeless teen, a dog that’s smarter than he is, and a yoyo? Oh, just trick some supervillains into becoming superheroes instead? You make it sound so easy!

Left dying in an alley, Mavis awakened the Retribution System, which granted him powers based on every humiliation suffered.

Smith lost his parents in a car accident, and his brother died some days after. He was left to take care of his sister, who was suddenly diagnosed with a brain tumor. Smith didn't have any money, and his wife would rather spend money to buy a bag than save his sister's life. He was looked down upon and teased in front of all families. When Smith thought it was all over for him, something surged within him: {Congratulations! Welcome to the lavishing system. Warning, you must spend 10 million dollars every day, or else, the system will depart}.

Noah Bennett was nothing but a “useless” son-in-law, mocked, slapped, humiliated. His wife cheated, her father cast him out, and everyone believed he’d finally disappeared for good. But fate had other plans. A mysterious black card, left behind by a dying stranger, transforms him overnight into a millionaire and unlocks a mission titled “Ashes of the Mega 7.” He must take down seven of the most powerful families secretly controlling the country’s economy each responsible for his past suffering, his parents’ mysterious death, and the corruption that rules the city. The first target? The Lewis family, his ex-wife’s bloodline.

Raymond Cooper was just a spy—until the skies split open. Alien invaders, the Morphidons, shattered Earth in a single night, and Ray became their top target. A shard of alien tech changed everything, fusing with his body to unlock the Apex Predator System—a power that transformed him from an ordinary man into humanity’s ultimate weapon. Thrust into an alien world to evolve or die, Ray returned to find Earth unrecognizable, its survivors waging a desperate war against extinction. Now, armed with powers he barely understands, hunted by galactic forces, and driven by the promise of survival, Ray must rise as humanity’s last hope—or see his world consumed. This is the story of a man who became a legend. This is the Apex Predator System

A nerdy engineer was brutally murdered with regrets in his heart. When he transmigrated into a magical world of Knights and Mages, he decided to live for himself this time around and to chase after his longtime dream- to start a big family filled with love and lots of kids from lots of wives! In order to protect himself and his loved ones in this harsh new world, he resourcefully forged era-ending weapons never meant to be fired in this world. To the Knights, Mages, Emperors, and even the Gods of this world, he proclaimed, “me transire, si audes! (cross me, if you dare!)”

I wasn’t reborn pure. I wasn’t reborn righteous. I was reborn unfinished. In a fractured fantasy world where cultivation advances through Marital Arts, power is forged through soul-bonds—vows that can elevate partners together or enslave them forever. Strength is no longer solitary. Love, betrayal, and shared destiny decide who ascends. Aren Valen awakens as the weakest outer disciple of the Azure Pact, carrying memories that should have died with him. In a past life, he was the Dragon Sovereign, erased at the brink of ascension by those he trusted most. Now, his Dragon Core is shattered and sealed, immune to orthodox cultivation. It awakens only through bonds freely chosen—not forced, not stolen. As ancient Dragon Veins stir, cultivation laws begin to collapse. Sects fall overnight. Empires rise on corrupted Marital Arrays that chain partners instead of empowering them. Defying all doctrine, Aren unlocks the forbidden Dragon Marital Codex, a path where power is shared without submission. Each bond awakens a Dragon aspect—Wrath, Wisdom, Dominion, Mercy—at a cost paid in trust and blood. Fate draws powerful women into his orbit: a sword cultivator haunted by memories of loving a Dragon, a rogue spirit alchemist hungry for forbidden truth, a fallen imperial princess seeking control, and a beast-blood warrior torn between instinct and reason. They are allies, rivals, and potential betrayers. But the past has returned. Aren’s former betrayers have reincarnated too, now ruling the new era—and they intend to erase him again by turning his own bonds against him. The Dragon needed a harem. The world is about to learn why.
