Kuro no Maou - Chapter 518

I had finally done it—achieved the ultimate Paladin build. Maxed stats, impenetrable armor, and so many resistances that death itself had given up on me. I was an unkillable tank, an indomitable force. Nothing could stop me.And then my PC exploded.I died.Irony, thou art a cruel mistress.But instead of the afterlife, I woke up as my Paladin character… in the wrong freaking genre. Instead of castles and dungeons, there were people flying around on swords, shooting qi beams like fantasy laser guns.“This is definitely the wrong genre,” I muttered, watching a pompous young master sneer at me.“Kowtow, kiss my foot, and beg for forgiveness!” he declared.I looked at my imaginary maxed-out health bar, then at his flimsy silk robes.Oh, this was going to be fun.

- Description from novelbuddy

Akira Tsukihara was a romance author who despised love. Though she wrote best-selling novels filled with idealistic romance, she harbored nothing but contempt for the genre and the readers who adored it. Love, in her eyes, was a lie—an illusion that blinded people from the true forces of the world: power, betrayal, and ambition. One night, in a fit of frustration, she cursed love itself... and woke up trapped inside one of her own stories.Reborn as Aira, a nameless peasant girl in the Kingdom of Seraphis—a world she had meticulously crafted—Akira quickly realizes that reincarnation isn’t the fantasy dream she had written about. She isn’t a noble, a princess, or a heroine blessed with beauty and power. She is a nobody. A commoner, struggling to survive in the harsh realities of the medieval world she had once designed as a mere backdrop for her grand romances.As Aira, she faces starvation, endless labor, and the crushing weight of insignificance. But Akira was never one to accept fate. If she couldn’t escape this world, she would rewrite the story on her own terms. She would carve her name into history—not as the lovestruck heroine of a cliché romance, but as the mastermind who would bend the world to her will.In a land ruled by noble bloodlines and political schemes, where the romance tropes she once loathed play out before her eyes, Aira sets her sights on one goal: destroying the very ideals of love that had imprisoned her in this wretched world.Even if it means becoming the villain of her own story.

Reborn as a sword, he lived for hundreds of years, and then he occupied the body of a 15-year-old prince.
