Ryuuk is depicted as a tall, gaunt Shinigami with a pale, almost translucent complexion and a skeletal face framed by a deep black hooded cloak. The figure captures his unnerving, otherworldly presence, with hollow cheeks and luminous green eyes that seem to pierce through the viewer. Delicate bone-white hands extend from billowing sleeves, while the wings are rendered as dark, membranous appendages folded behind the figure, giving a sense of looming flight. The cloak drapes dramatically, with subtle gloss to hint at a supernatural texture. The character stands atop a subtle, uneven base that nods to his ominous nature, perhaps with an apple motif. The sculpt emphasizes gaunt limbs and elongated fingers, conveying both elegance and menace. Painted shading enhances the sunken features, with soft gradients from grey to ivory and fine cracks in the cloak to suggest age. Overall, the figure balances a macabre aura with a refined, display-friendly silhouette suitable for a shelf or display cabinet. The 1/10 scale is evident in the proportions, allowing fine detailing on the cloak's folds, the contour of the skull-like head, and the careful texture on the wings.

Ryuk is a Shinigami who observes humans for entertainment and curiosity, bound to a Death Note as part of a cosmic game rather than loyalty to any side. He travels between the realms to witness how a single choice can ripple through lives, often dropping into the human world to provoke or simply observe. In the story, Ryuk encounters Light Yagami and later interacts with others, orchestrating intricate and morally ambiguous situations that reveal the complexity of humanity. He famously adores apples, a simple pleasure that contrasts with the weighty responsibility of judging souls; this quirk adds a touch of dark humor to his otherwise chilling presence. Through the Death Note, he acts as a mysterious observer who occasionally guides outcomes while maintaining a detached, amused demeanor. The character's presence creates tension and drives pivotal scenes, exploring themes of power, judgment, and the consequences of playing god.
