月霜の刃 - Blade of Lunar Frost
The story of the Smiling Snowstorm begins...
In a world where demons roam beneath the shroud of night, one girl's fate is carved in frost and blood.
Shirogane Yuki (白銀 雪), once the eldest daughter of a strict and merciless household, dreamt of proving her worth by joining the Demon Slayer Corps. But her failure only earned her scars - not from demons, but from her own family's cruelty.
One winter night, everything changed. The silence of her cold home shattered into screams, the sound of flesh tearing under demon claws. Paralyzed by fear, Yuki chose survival over courage, watching her family perish. When the chaos ended, only silence and snow remained - and the absence of her twin, stolen into the darkness.
Now branded by guilt and driven by a twisted will to live, Yuki forges her path with the Lunar Frost Breathing. Wielding her crescent Moonfang Scythe and bloody chains, she dances between elegance and madness, smiling even as the battlefield drowns in blood.
But beneath her sweet smile hides a storm.
Is she a savior... or a demon waiting to be born?
