Justice is Blind |『 Female OC 』• Kimetsu no Yaiba

Act 31: A Fateful Canvas

The air around Shirayuki hummed softly as she continued her descent through the endless labyrinth of the Infinity Castle. Despite the chaos, Shirayuki remained calm, humming quietly to herself as if she were simply enjoying a peaceful evening walk.

The sensation of falling had become oddly familiar, and she showed no sign of concern. Her grip on the bento box she had been savouring was loose, her fingers idly tapping against its edge. But her senses were sharp, and she could feel the presence of something nearby.

*Whoosh*

Shirayuki's lips curved into a small, knowing smile. She let go of the bento box without hesitation as it drifted away into the endless expanse beneath her. Her hands shifted, moving with fluid grace as she reached for the hilt of her sword. The demon lunged at Shirayuki from her right, eager to tear into its prey.

*Click*

*Swoosh*

Shirayuki used its body as a stepping stone as the demon closed in. Her movements were effortless, her sword a mere blur as she twisted mid-air, planting her foot on the demon's back and launching herself toward the nearby platform from which she felt the demon jump. The demon snarled in frustration, its jaws snapping shut close but only to air.

Shirayuki landed lightly on the platform, her feet barely making a sound as she straightened. Her sword was already drawn, the blade gleaming in the dim light of the castle. With a flick of her wrist, she twirled her sword in a graceful arc. "Ice Breathing Fifth Form:..." she lingered softly.

Her blade moved so swiftly that the demon didn't have time to react. For a moment, the demon's head remained on its shoulders, eyes wide with shock. "Silent Frostbite," finished Shirayuki.

*Click*

Then, Shirayuki sheathed her sword, and the demon's head rolled off, its body crumbling to dust soon after. Shirayuki hummed again, the sound almost playful as she tilted her head, listening to the world around her.

The castle was alive with movement, from footsteps echoing through the endless halls to the distant clashes of swords against flesh and the guttural roars of demons. The sounds reverberated off the walls, creating an eerie symphony that filled the air.

Her senses flared, and she shivered slightly as she detected a strong heat signature, burning like a roaring flame. It was unlike anything she had ever felt, a concentrated intensity that sent a chill down her spine. Her hand instinctively gripped the hilt of her sword as she turned her head toward the source.

Shirayuki's blind gaze narrowed, focusing on the northern direction where the heat originated. It wasn't just strong but overwhelming, a pulsating force that seemed to dominate the entire castle. Her breath hitched slightly as a thought crossed her mind.

'Could it be...Muzan?' she wondered. The idea lingered in her thoughts for a moment, the sheer possibility of it sending a thrill through her veins. But before she could delve deeper into that idea, a new wave of movement reached her senses.
