Demon Slayer: Nezuko's Heartbeat

[Demon Slayer fanfiction] [Transmigration to another world] [System] [Redemption]

I’m Lin Xiaoxiao, a fresh graduate and corporate wage slave. I transmigrated after being hit by a car while saving a cat, only to wake up as my favorite character’s daughter: Nezuko! It’s hell mode from the start: a bamboo muzzle over my mouth, my older brother Tanjiro is a walking death flag, and the future plot is packed with tearjerkers.

But my greatest golden finger isn’t the System. It’s my “foresight” of every character’s tragedy and my inability to stand by and watch. The corporate-slave spirit burns bright within me, and I’m determined to rewrite this blood-soaked tragedy with “emotional resonance,” a weapon that completely outclasses the opposition!

I use an abstract map to spoil the Final Selection, and the warmth of family to block a lethal attack. I go to Rui on Mount Natagumo and pour real familial love into his frozen heart. At the Entertainment District, I roll my eyes and mock Daki’s sashes as “Yiwu knockoffs,” then hand the Sound Hashira a walkthrough written in ugly handwriting. I hug the Mist Hashira, whose memories are shattered, and hum a nursery rhyme to help him find himself again.

Rui breaks down in front of me. Akaza gives up regeneration for love. Kokushibo loses his composure at the word “brother.” When the final battle arrives, I unleash the [Heart’s Domain], linking every member’s emotions and strength into a network. Sanemi feels Shinobu’s pain, Zenitsu is enveloped by Rengoku’s courage, and everyone’s attacks become a grand symphony!

I am Lin Xiaoxiao, and I am Nezuko Kamado. With a mortal heart and the power of the gods, I will reshape every regret! But... Brother, after we beat Muzan, can you get me some cola and fried chicken? I’m really sick of bamboo-tube rice!
