Betrayed. Ridiculed. Killed.That was my past life.I trusted the wrong people, and they buried me for it. But fate wasn’t done with me yet. When I opened my eyes again, it wasn’t in my old body—it was in a world overrun by the undead. And this time, I was one of them.A fucking zombie!But I’m not like the others. I think. I feel. I remember.What’s this voice in my head?[Welcome to the Silent Requiem System!]The system feeds me power, unlocking missions and skill buried within this body. I have one goal: rise in rank, take control, and make sure no one ever tramples me again.The humans I move with have no idea what I really am. To them, I’m just another survivor, clawing my way to the top. But in battle, I use my abilities in secret—manipulating the undead, eliminating threats, and turning every fight in my favor.But rumors are spreading. There’s talk of an undead hiding among them, unseen and unstoppable. If they find out the truth, they’ll hunt me down like a monster.And my past? It’s here too. The people who betrayed me in my last life are standing right beside me, unaware of who I am. But I remember them. They turned on me once—I won’t give them the chance to do it again.Then there’s him. The commander of the city, sharp-eyed and ruthless. He’s watching me too closely, asking too many questions. If he figures out the truth, I’ll have to make a choice: eliminate him, outplay him… or pull him into my trap before he can destroy me.Because in this world, power is the only thing that matters. And this time, I refuse to be at the bottom.***“How did you survive when everyone else died?”I guess death just didn’t want me.“Why do the zombies ignore you?”Maybe I just have a face they don’t like.“You were just a nobody yesterday—how are you suddenly so strong?”Hard work, luck… and a little bit of hex.“Why do I feel like I've seen you somewhere before?”Déjà vu’s a funny thing, isn’t it?“What are you?”Wouldn’t you like to know?

Reincarnation in a game as the Main Antagonist.It could be a novel itself, but that was what I dragged myself into. In the famous and successful game [Princess And Dragon]As if my life wasn't shitty enough, a bastard brought me in that hardcore violent Dating Sim Game and in the body of the worst villain and [Major Antagonist Edward Falkrona]If I want to survive, I have to become strong.If I want to be strong, I have to join the Academy and by joining the Academy, I will meet these guys...Yeah, I'm obviously speaking about the Protagonist, the Main Heroines, the Villainess and all the villains.Am I destined to watch that protagonist build his harem in front of me?!

The world was never the same after that day.Humanity learned that they weren't alone in the universe, but that wasn't something they had the time to worry about.Their realization was accompanied by catastrophe.Creatures beyond their wildest imaginations poured down from the sky and appeared from the earth. They slaughtered humans as if it was their singular purpose, driving them to the brink of extinction.The people of the world did everything in their power, developing unique traits and technologies to create a united front their enemies couldn't penetrate.They secured victories and repopulated, feeling as if they stood a chance against the foreign invaders.They fought and they fought, doing everything they possibly could to ensure their survival.Until the Great Calamities appeared.In front of them, humanity was nothing regardless of its efforts.One by one, the worlds were turned into piles of rubble in between the cracks of their teeth. Civilization was torn apart, and the evolved humans living within could do nothing to stop its collapse.Humanity itself was left extinct, and in the end, only a single man was left alive amidst the chaos.Why?For what reason were they punished so?Nobody knew why the attacks began in the first place.He looked into the distance at the memories of the past and firmed his resolve.“It can only be me.”He knew of a miracle that could return him to the place of those memories.He knew of a way to make the wheels of time spin in reverse.And using it, he alone would save humanity from its doomed fate.That was his sacred duty as its final survivor.
