Vampires x Devils: Annihilation Master

I got isekai'd into a monster academy. My vampire "friend" wants my blood. The other students want me dead. Joke's on them. I have a System that lets me grow stronger by defeating and slaying any monster that crosses me. Yokai Academy is supposed to teach monsters how to blend in with humans. But the only lesson I'm learning is that power is the only thing that matters here. So I'll take it. From every one of them— be them orcs, salamanders, mermaids, werewolves, flaming kitsunes with murderous tendencies—all of whom view me as prey. You think I'd hide behind my vampire girlfriend? That was your first mistake. I'm human, but I'm also a transmigrator. And a transmigrator always comes prepared. I have a Sacred Gear waiting to awaken, with a power that could shake the supernatural world, even if I'm not ready to wield it yet. My Vampire Princess is a badass—and she's about to turn me into one of her kind. I have a Gremory Heiress waiting to be found, a devil who could change my whole status. And an ambition that reaches from the Heavens to the Abyss. This world isn't ready for the new Dark Lord, Aono Tsukune. --- Disclaimer: This is a fanfiction crossover where various characters from other fandoms will appear thanks to the nature of the Annihilation Maker. The main worlds, Rosario + Vampire belongs to Akihisa Ikeda and High School DxD/Slash Dog belongs to Ichiei Ishibumi. I own only the original plot and my transmigrator's terrible decisions.

In the World of Detective Conan with a Choice System

Transmigrating into a nightmare is one thing; waking up as the prime suspect in a "locked-room" murder is another. When Akikawa Kosuke opens his eyes, he isn't in a hospital or a peaceful new world. He is trapped inside a sealed, crashed boxcar, his body leaden and his mind reeling from carbon monoxide poisoning. Slumped over him is a woman, gruesomely stabbed to death—and his own hand is still clutching the hilt of the murder weapon. With police sirens wailing in the distance and a mysterious "Option System" flickering before his eyes, Kosuke realizes he has seconds to act. He has no memory of the original owner’s life or whether he is truly a killer, but he knows one thing: if the police find him like this, his new life ends before it begins. A desperate race against logic and evidence begins. In a chilling display of resolve, Kosuke uses his medical knowledge to systematically destroy the evidence against him. To sever his connection to the weapon and the crime, he must go to extreme lengths—even if it means deliberately shattering his own bones to create a physical impossibility. But as the doors are forced open, Kosuke discovers he isn't just facing the local police. He has transmigrated into a world where the "Death God Elementary School Student" exists. Under the piercing gaze of the world's most famous detectives, can Kosuke maintain his innocence, or will his own cover-up become his undoing? What to expect: Mc who will break his own body to manipulate a crime scene. High-stakes decisions that grant skills, traits, and survival. Prove your innocence when you are caught red-handed in a locked room. This is only a translation. Here is the original source: 人在柯南,有脑内选项系统

Douluo Continent: Twin Spider Queens, Rebellious Against Their Master

Good news: I've transmigrated! Bad news: The system paired with the wrong person! Good news: Out of humanitarianism, the system abandoned the Death Spider King and Soul Devouring Spider King, the Soul Spirit Secret Technique, and Huo Yuhao's Soul Master inheritance as compensation before running away. Even better news: I have a third Martial Soul! And it's a Body Martial Soul! But there's even worse news: This Martial Soul possesses ultimate divine, gold, and spiritual attributes! It's time to give the natives of Dou Yi some Soul Tools—it's amazing! When the Twin Spider Queens appeared, Lin Fan only wanted to become Bibi Dong's disciple, hoping to use her resources to help him grow, but he never expected... Bibi Dong: "Come and practice your Martial Soul Fusion Technique tonight..." Qian Renxue: "What do you mean by possessing the ultimate evil, ultimate death, and ultimate holiness—three ultimate attributes? Who is the true Martial Soul of God, the descendant of the gods?!" Hu Liena: "Little Fanfan, don't move, let your senior sister give you a squeeze~" Auspicious Beast: "Lin Fan, I see in destiny that you are the hope of the Soul Beast race!" Tianmeng: "Hehe, following Lin Fan means you'll get to eat meat! I'm the first Soul Spirit in this world, I'm going to become the God of Soul Spirits! " Tang San: "Why is a Soul Guidance Device stronger than my hidden weapons?!" While others were throwing Soul Skills and hidden weapons, Lin Fan directly manipulated his metal hands to create a Soul Guidance Cannon. He directly transformed his Martial Soul fists into metal, with high damage on both the left and right fists! The Holy attribute came with dissolving and purifying abilities! ~~~~~~~~~~

Overlord: All Hail Brainiac the Collector

Before the final curtain falls, before the gods abandon their hollow heaven, Momonga commits one last, quiet heresy: he abdicates. The throne is not left empty—it is entrusted. To Brainiac. A name that hums like circuitry and lingers like a verdict. He does not rule so much as revise. With a tactician’s patience and a playwright’s cruelty, he reshapes Albedo’s story—trimming hope, amplifying devotion, editing fate line by line. Not mercy. Not chaos. Precision. And yet— Beyond the throne, beyond the illusion of power, Brainiac is a man already half-erased. His bones are glass in denial. His muscles, a rumor. His heart, a failing metronome counting down a sentence passed at birth. They called it a rare genetic disorder—a clinical euphemism for a life written to end early. Twenty years, they said. He made it to twenty-six. A miracle, if one enjoys irony. Now he lies in a hospital bed so sterile it feels like a prelude to burial. Machines breathe for him with tireless indifference—inhale, exhale, repeat—while his body negotiates with gravity and loses. Walking is memory. Strength is myth. Survival is habit. But in Yggdrasil— He was whole. He was feared. He was alive. So when the end approaches, when the clock begins its slow, smug descent to zero, Brainiac makes a decision with unsettling calm: “Unplug it.” No grand speech. No trembling hesitation. Just a quiet exit, delivered like a mundane request. Dark humor at its purest—after all, why outstay your welcome in a body that never wanted you? Let the game end. Let the body follow. Let oblivion keep the schedule. The countdown reaches zero. And then— It ticks. Once. Again. Persisting. Not silence, but continuation. Not an ending, but a contradiction. A cruel joke with no audience. A resurrection without permission. And Brainiac—king in one world, dying in another—finds himself suspended between them: A throne he never earned. A death that will not arrive. And neither will release him. All rights reserved.
