Kimetsu no Yaiba: The Flower Beneath Divine Shadow

[Female Protagonist • No System • Demon • Muzan’s Side • Demon Slayer] My name is Tsugikuni Rin. The younger sister of the Child of God. An Upper Rank Demon of the Twelve Kizuki. Muzan Kibutsuji’s most trusted secretary. The thief who stole the power of the gods. The manipulator of fate. The only usurper of divine authority in the world. And for centuries… the Demon Slayer Corps’ greatest nightmare. Born as the youngest daughter of the legendary Tsugikuni Clan, Rin Tsugikuni was nothing more than a pawn in the gods’ grand design. Cursed with a body that had been rotting since birth and forced to bear the burden of a clan abandoned by her two prodigious older brothers—Yoriichi and Michikatsu—Rin spent her entire life imprisoned within the cold walls of a lonely castle tower, living as nothing more than a puppet. Yet behind the mask of quiet obedience, she harbored an overwhelming hatred for the script of fate the heavens had written for her. When death came for her at a young age, Rin refused to surrender to a meaningless end. Determined to shatter the chains of fate that dictated both her life and death, she committed the ultimate taboo—trading away what remained of her humanity for the power of darkness. She rose again. Not as a human… But as an existence the gods themselves could neither predict nor control. In a world where destiny had long been set in stone, Tsugikuni Rin became the one who dared to tear apart the heavens’ script. Years later, during the final battle against the Demon Slayer Corps within the Infinity Castle, Tsugikuni Rin would remember that quiet morning… The morning she took young Yoriichi to watch their older brother practice swordsmanship.Perhaps…From that very day, the fate of the three Tsugikuni siblings had already been decided.P.S.The female protagonist is a demon who serves under Muzan, not a demon infiltrating or disguising herself within the Demon Slayer Corps. — Description from novelcodex.orgFull novel: Kimetsu no Yaiba: The Flower Beneath Divine Shadow — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
