But when his birthday comes, everything changes. His body feels stronger, his senses sharper, and women—especially the ones around him—start acting strangely, drawn to him in ways he doesn’t understand.Then, the truth hits him—he’s not human. He carries the Incubus Bloodline, the rare male counterpart to a succubus. And his adoptive family? They’re not just powerful superhumans. His stepmother, Lilith Nocturne, is the Succubus Queen, and his three stunning stepsisters are Succubus Princesses—rulers of an entire fantasy planet.But here’s the strangest part—they don’t know what he really is.As Ethan struggles to make sense of his new reality, he learns that the world’s superpowers aren’t as simple as people believe. Fantasy creatures—elves, vampires, dragonkin, and more—aren’t just myths. They’re real. And they’ve been living in secret among humans.Now, they’re appearing in his life, drawn to him for reasons he can’t explain. His bloodline, his awakening, and the system guiding him—it’s all connected to something much bigger.Why have these races stayed hidden for so long? What is the real truth behind superpowers? And why does he feel like his very existence is meant to change everything?With a system pushing him toward his incubus instincts, powerful women from all over the world—and beyond—falling into his orbit, and forces in the shadows watching his every move, Ethan has two choices—fight it or embrace it.But one thing is clear—his life will never be the same again.

All Raven ever wanted was a chance — to go to college, make friends, be loved, and live like any other girl her age. But dreams, it seemed, weren’t meant for people like her.As a scholarship student at an elite university built for the wealthy and privileged, Raven's life quickly spiraled into a nightmare. Surrounded by cruelty and entitlement, she became the perfect target. Their relentless torment stripped her of everything — her dignity, her hope, her will to live. She bore it all in silence, blaming herself even for the tragedy that tore her family apart. Despair led her to the edge of suicide, but fate had other plans.Ten years later, those same bullies, now living lavish lives of success and luxury, had long forgotten the girl they destroyed. But Raven hadn’t forgotten them — not one bit.With scars that ran deep and a heart hardened by pain, she returned — no longer the fragile girl they once broke. One by one, she would visit her tormentors, delivering her own brand of justice and making them learn that every cruel action has a consequence.Because this time, Raven isn’t the victim.She’s the reckoning!
