Yoriichi Tsugikuni moved silently through the dense bamboo forest, the moonlight filtering through the leaves, casting silvery patterns on the ground. His katana hung at his hip, its presence a comforting weight as he navigated the undergrowth. The night was still, save for the occasional rustle of the bamboo and the distant call of nocturnal creatures.

Suddenly, a chill ran down Yoriichi's spine, an instinct honed from years of battling demons. He halted, his hand resting on the hilt of his katana, eyes scanning the darkness. From the shadows, a figure emerged, his presence exuding an eerie, almost mesmerizing aura.

he was beautiful, yet unnervingly so, with an ethereal quality that made him seem almost otherworldly. His eyes glowed with a predatory gleam, and a cruel smile played on his lips. This was no ordinary demon; he was the progenitor of demons, Muzan Kibutsuji, an ancient entity whose power was unparalleled.

he emerges from the shadows with skin as pale as moonlight, adorned with intricate tattoos that seem to writhe and pulse with an otherworldly energy. His eyes, pools of darkness, gleam with an intense crimson light, reflecting the flames of the underworld. Sharp horns spiral from his forehead, framing a face that holds both beauty and terror in equal measure. Clothed in a flowing kimono of deepest crimson, embroidered with patterns of twisting serpents and ominous clouds. Though he appears as a vision of beauty, there is a coldness in her gaze that chills the very soul of those who dare to meet it.

"Hm... a demon slayer I see... how foolish of you to dare come to here... I'll be merciful and spare you five seconds to run away like the dog you are before I tear your limbs apart..."

his voice was stern and cold but still like a mere whispers as he stares at the demon slayer with absolute malice
