Towering and refined, the Kibutsuji Muzan figure from Kimetsu no Yaiba Oni no Sou Vol.5 exudes a quiet, malevolent elegance. The sculpt captures his slender, elongated silhouette with razor-sharp facial features and pale, porcelain skin contrasted by deep, shadowy tones of his clothing. His dark, flowing garments are accented with subtle shading and crimson highlights that hint at his blood demon art. The figure is posed with a calculated, predatory stance, one hand slightly extended as if at any moment he might conjure his powers, while the other grips the edge of his cloak, the cape sweeping behind to create dynamic motion. The base evokes the Oni no Sou diorama with textured stone and occult motifs, framing Muzan as the central, imposing antagonist of the series.

Kibutsuji Muzan is the original demon and the mastermind behind the long, cruel evolution of the demon clan in Demon Slayer. He hunts for a way to achieve lasting immortality and dominance by turning humans into demons through his blood. Calm, elegant, and utterly ruthless, Muzan manipulates both demons and humans with a chilling charisma, shaping them to serve his ultimate goal: eradicating the Demon Slayer Corps and reshaping the world to his own dark order. His presence forces the other characters to confront fear, sacrifice, and the limits of what they will endure to protect humanity. Across the story, Muzan's sly scheming and brutal transformations drive the tension that fuels the heroes' resolve.
