From the Oni no Sou line, this Bandai Spirits figure of Hantengu presents a commanding, dynamic silhouette that captures the demon's menacing presence. The sculpture emphasizes Hantengu's signature feral features: curved horns, night-black skin with subtle violet shading, and jagged fangs visible in a silent snarl. Extraneous armor-like plating along the arms and shoulders is sculpted with crisp edges and fine texture to convey a demon's hardened exoskeleton. The figure stands in a poised combat stance, weight shifted, with one hand extended as if weaving ominous energy. The paintwork uses layered shading, dry brushing, and metallic accents to highlight muscles, folds in the clothing, and the unsettling red aura surrounding the form. Transparent resin effects can be seen around the hands and base, suggesting the character's supernatural emanations. The overall presentation is dramatic, intricate, and true to the source material, ideal for display in a collector's cabinet.

Hantengu appears as a demon who embodies fear and the unknown, a foe whose power is not a single attack but a cohort of alternate forms. In the story, he manifests by splitting into several avatars, each representing a core emotion and presenting unique combat patterns that challenge the Demon Slayer Corps. The heroes encounter him in a tense chase through shadowed ruins, where cunning, timing, and teamwork determine whether they can exploit a momentary weakness before his forms regroup. The Oni no Sou figure embodies this chaotic duality: a single statue that hints at the demon's segmented nature, with separate energy auras and sculpted shifts in texture to suggest different forms. The narrative explores the danger of underestimating a foe who can adapt shape and strategy on the fly, turning a straightforward duel into a battle of wits and endurance. This background makes the figure a compelling centerpiece for fans who appreciate the character's enigmatic menace.
