Starlight in the Ashes (demonslayer fanfic)

A Demon Slayer fanfic | Akaza's foundling. Rengoku's star.

"He found me in a crater. Raised me in shadows.
But I was always meant for the light."

Raised by a demon. Forged by starlight.
Yuki never asked to be special-yet the blood in her veins could change everything. Hidden for years by Upper Moon Three, she was trained to survive, to kill, and to never be seen. But fate had other plans.

Now sixteen, Yuki steps into the world of the Demon Slayer Corps with a wooden sword, a secret past, and a breath style all her own: Star Breathing-a radiant dance of cosmic power no one has ever witnessed.

Her mission? Infiltrate. Observe. Report.
Her mistake? Falling for the Flame Hashira.

Kyojuro Rengoku is everything she was taught to avoid: bright, brave, and kind in a way that terrifies her. And yet, with every clash of blades and brush of hands, Yuki finds herself pulled toward a future she was never supposed to want.

But the stars are watching.
Muzan is hunting.
And her past is catching up fast.

✨ What happens when the demon's daughter falls in love with the one sent to kill him?
✨ What happens when a star refuses to fall?

Romantic slowburns, secret bloodlines, training arcs, soft Hashira moments, and one very chaotic crush.
