The gears of fate are never gentle. Takamachi Nanoha, the magical girl with starlight as her armor and faith as her blade, after quelling the restlessness of the Holy Stone Seed, sealing the curse of the Book of Darkness, and shattering the conspiracy of the Eternal Crystal, she was still pushed into the unknown abyss by fate. During a certain mission a few years later, a force that tore apart time and space dragged her into another world.
She looked around blankly, holding the strangely patterned sword tightly in her palm - it was also the one that led her into this place where evil spirits were rampant.
As the original ghost and the absolute ruler of ghosts, Onibatsuji Mukai's name has already seeped into the bone marrow of the world like poisonous mist. The first moment Nanoha set foot on this land, the whisper of the world sounded in her ears. The sound was neither wind nor rain, but the screams of countless dead souls, weaving an airtight net in the void.
As a magical girl, her usual magic has long since expired. Only breathing can activate the remaining magic in her body.
After killing the first evil ghost, the Nichirin Sword in her hand, which was composed of a sword and her own magic power, suddenly seemed to have self-awareness, leading her to cut through the barriers of time and space.
From then on, she began to wander in the intertwined history of the Demon Slayer Corps and evil spirits. At that moment, her white figure began to become an indelible nightmare in the eternal life of Onimbutsuji Muzan.
PS: There is no ambiguity about Nanoha's CP, and all members are interested in redemption. There will be a destined offspring, the offspring of Komaharu and Koiyuki, Tomioka Oriko survives, Fengzhu's mother and younger siblings all survive, Butterfly Kanae is confirmed to survive, and all the children adopted by Iwazhu survive!
