Almighty God System (R-18)

Uther Pendragon is dead, and in his last breath, a degenerate soul overtook his body. He was granted the Ero System. His first task? To bang Morgan le Fay as soon as he woke up from death’s door. [Evil MC]

My name is Clovis la Britannia. You probably don’t remember me, just another forgettable prince killed by Lelouch in his first act as Zero. Except this time… I’m not just a Clovis. I’m a guy from our world who woke up as him. C.C. is in my basement. Lelouch is on his way to kill me. And somehow, I made a Geass contract before the plot could kill me. Only... my Geass doesn’t control minds. It controls desire. Anyone I make eye contact with becomes hopelessly, obsessively, violently attracted to me. What started as a fun little power turned into a curse of yandere, overpowered waifus, and women willing to burn the world just to keep me. Lelouch? Good luck, buddy. I’ve got a harem of yandere ready to murder you for looking at me wrong. This is no longer his story. It’s my story, story of Clovis la Britannia.

My life is amazing. I have OP Power. I have a Chat Group. I have a great bloodline, and I have a cute but sadistic sister. Oh, and I also have a gullible sister. So, in total, I have two vampire glorious sisters. Well, who am I complaining to anyway? You know them. If you still don’t, allow me to introduce them. They are Arcueid Brunestud and Altrouge Brunestud, and they are my sisters. As the only man who survived among the True Ancestors, it’s my duty to keep the bloodline pure and repopulate the Brunestud Bloodline with them. This is my story, my True Ancestor story, and my rise as the King of the Vampires, then the world. Let the conquest begin. [Multiverse Conquest] [Chat Group] [Incest]

All I wanted was to chill—but nah, Truck-kun didn’t give a single fuck about what I wanted and slammed my ass straight into another world. Now, I’m stuck in the Nasuverse, living under the same roof with a girl who can flex omnipotence and omniscience whenever she wants. Sajyou Manaka. My sister. A girl with a god complex. Fine. Whatever. I’ll live my own life. …Except, every girl I date? Mysteriously sent overseas. Their families? Suddenly relocated for work. And the one responsible? Manaka, smiling sweetly as she whispers: "I’ll be everything you need instead." So, I did what any Gigachad would do. I lifted her chin… and kissed her. Now, it’s time to fix her. [Evil MC]

A nerd with skill issues getting girls found himself transmigrated into an anime fusion world, but to his surprise, it’s a gender reversal world where the positions of men and women are flipped. It’s women who are responsible for work, while males take care of the household. Females have a higher sexual drive and are more dominant in society, while males are expected to be meek and submissive. Well, at least, it was easy for our nerd MC to get the girl in this world, considering his loser status in his past life. What could possibly go wrong?

I was reincarnated into COTE and my sister is none other than Arisu Sakayanagi. Unlike other normal siblings, we have already done plenty of sex before we even go to Advanced Nurturing High School, the school where canon events take place. My sister is sweet, smart, and flirtatiously cute, but when I introduced another girl into my life whom I saved from a bullying incident, she changed. And it was also the time when hell began to break loose.

You died and found yourself as Makima Asmodeus, the Control Devil and one of the Four Satans of the Old Satan Faction, destined to be crushed by Sirzechs and his ilk. Yeah, sounds like a great start, doesn't it?

John used to be a bright young man. He had positive values and good moral outlooks toward life, but his death changed everything. Finding himself reborn in an anime fusion world, his mother threw him away into an orphanage right after giving birth to him. What made matters worse, the place was run by a shady organization that forced all the children to be trained as assassins. Luckily, he succeeded in his scheme to run away from the orphanage with his sister, Yor Briar, and was later adopted by the Sakayanagi Family, becoming the brother of Arisu Sakayanagi. Ten years later, Dimensional Game Online was launched, every anime from his past life turned into a VR game that everyone could play. However, as soon as he logged into the game, he discovered a bug. He could choose some hidden boss identities in-game and inherited all their power and background. While everyone else struggled with grinding, he had already become the Third Magician, flexing his OP powers. Behind the scenes, he controlled Roman Empire, manipulating the Holy Church into becoming the single most dominant religious force the world had ever seen. He established the Burial Agency, slaughtered True Ancestors, and while nobody knew it, he was banging the Empress of Rome herself. Oh, and yeah, he was secretly the Pope too, all along. In Seraph of the End, he was the Demon Emperor, formerly the Third Progenitor Vampire and beloved brother of the Vampire Queen, Krul Tepes. He was the one who ruled over both Seraph and the Apocalypse. While other players scrambled just to survive the Apocalypse, maybe busy glazing over Saeko Busujima’s bouncing tits, our MC had already owned both the bitches and the empires. As soon as players entered the DXD world, they were brutally slaughtered by stray devils. But what about our MC? He was the God of the Bible and his soul had fused into Cao Cao’s spear, of all things. But instead of being some wise old ghost giving cultivation advice and ancient alchemy techniques, he said fuck that. He hijacked Cao Cao’s body, took over everything. From that moment on, the God Emperor was born. By the time players looked back, they realized the horrifying truth. They hadn’t run into a hidden boss… They ran into a hacked account. [Evil MC] [Massive Harem] [Multiverse Conquest]

What if you woke up in a world full of idiots with the intelligence of toddlers? Despite having only above-average intelligence on Earth, you quickly become the smartest, most creative, and most brilliant person ever to walk the planet. This isn't your average DanMachi. It's a version of DanMachi where every inhabitant has an extremely low IQ, and you're the only truly intelligent person in the world. Can you build an empire and a harem in a world full of idiots? Find out in this story! Note: We've all seen countless fanfics that dumb down every character except the MC just to make the protagonist look like the smartest genius alive. What if we stop pretending and just admit everyone is stupid and only MC is smart one? This is the story of...

A dopamine junkie with a porn addiction wakes up in Guilty Crown just in time to get forcefully kissed by Mana Ouma, the protagonist's yandere sister. Instead of panicking, he kisses her back while her brother watches. His philosophy is simple: who cares about canon? Chase girls, power, and highs. That's the only thing that matter

Born out of hate sex between Zelretch and Crimson Moon, you are born. Yeah, good to be you, indeed or lack thereof. You are surrounded by prick vampires who think they rule the world. Your older sister is also a pure sadist and a sociopath, and your younger sister is at least sweet, sweet but psycho, maybe? Your father hated you as he hated Crimson Moon, and your mother basically wanted to use you for her resurrection. The only consolation prize is that at least you are a vampire. A fucking vampire. You are also a fearsome creature known as a True Ancestor. A peak predator in the Nasuverse and on Earth. You inherited the strength and bloodlines of the two most powerful forces in the Nasuverse: Zelretch and Crimson Moon. Any other MC would focus on chasing the approval of their parents and being a cringelord who lacks maternal love and friendships that could warm their heart, but you? You choose violence... And violence you did.

Cursed by the God Ankhseram for trying to resurrect his brother, Natsu Dragneel, Zeref should have been doomed to endless despair. But when his curse reached its weakest moment, something far worse answered. A soul from beyond this world seized his body—claiming Zeref’s limitless knowledge, genius intellect, and god-tier magic… without the curse. Immortal. Unchained. Unrestrained. This Zeref doesn’t seek death. He seeks power, conquest, and every pleasure the world dares to offer.
