Once a kind-hearted soul, Lucien’s second life spirals into tragedy. After witnessing his family murdered and his pleas for mercy ignored by their killers—his own blood relatives—he awakens his true ability: the power of Creation through Conceptual Memory. From every anime, comic, video game, or story he ever encountered in his past life, Lucien can mutate reality—not by creating life, but by twisting it. But before he can understand what he truly is, he and Elian are captured by a secret mutant experimentation facility. Tortured, violated, and transformed into test subjects, Lucien breaks—only to be reborn anew. From the ashes of that pain, Lucien designs the ultimate power: the Oblivion Frame, rendering him utterly untouchable by all powers—magic, psychic, cosmic, divine, or even physical. Time cannot touch him. Death cannot claim him. He becomes an immovable paradox in the multiverse. With Elian at his side, Lucien unleashes his vengeance through a dark and beautiful innovation: the Mutation Seed—a black-market biological bomb of chance. When consumed, these seeds rewrite a host’s DNA, granting random powers from legendary fictional characters, but never altering the body’s form. Most seeds offer a single ability. Some grant multiple powers. A few—one in a million—create monsters and gods. Lucien begins flooding the multiverse with these seeds, offering chaos for sale to the highest bidder—and the lowest scavenger. Governments collapse. Mutants evolve. Gods fall. And from the shadows, a new empire rises—not of kings or politicians, but of powerful mutants born from fiction and forged by rebellion. He does not seek conquest. He seeks collapse. For Lucien is not a savior. He is not a villain. He is the Author of Anarchy. The Seed of Ruin. And in the garden of reality, He has begun to sow.

Kenshi Kuraka's quirk is a double edged sword. Powerful in its own right, but with a drawback that would stop most from using it. Kenshi doesn't care though, because he WILL be a hero, just not one who basks in the light. An underground hero, one who will aspire to make a real change to a city that never sleeps, even if a century old villain wants to keep it that way. Hopefully, with the help of a dry eyed teacher, friends who want to push him to work hard, and attending one of the best hero schools; Kenshi can achieve just that.

I wrote a book once. It was an unhinged fantasy born from my high-school brain, driven by loneliness and too many hormones. It was a world of beastmen, wild freedom, and the kind of romantic attention I could never get in real life. I poured every impossible desire into it: adventure, danger, and yes… a 'lot' of handsome partners. Before I knew it, I had a thousand chapters of pure escapism and pure thrill. Then on a college camping trip, I fell off a cliff. I expected to wake up in a hospital room but nope. I woke up on a soft field of grass, with air too fresh to belong anywhere on Earth. And then something moved behind me. Sticking out of my tailbone was... A tail. My tail? Yellow and black stripes and very, very real. I touched it. Completely real. My ears? Also gone—well, moved. They were now perched on top of my head like a confused jungle cat. And the outfit? Quite revealing, made of animal hide which matched my tail. What was going on? At first, I thought it was a prank. Or a dream. Or maybe karma is finally cashing in. But the more foreign memories evaded my mind, the clearer my situation became. This wasn't cosplay and it wasn't Earth, either. And—surprise—it wasn't even the world from my own book. Welp. I had been transported into a completely different Beastman world as a beast girl called Arinya. Sounds fun, right? Well… it would be, if I weren't apparently the ugliest duckling in the entire freaking savannah! Rejected by every potential mate I stumbled across and sneered at like a freaking eyesore. This was not how I planned my fantasy to come to reality. Trust me—if this is my fantasy come true, then someone needs to fire the author. But then again, after entering this world, I'm suddenly... Attractive. I mean, there's no change to my face and the freckles are still there, but for some reason, handsome beastmen begin to flock around me, because I smell... Pleasant. What's that all about?
