Koenma is depicted in his signature royal attire with a long blue robe, golden trim, and a small crown perched atop his youthful brow. The figure's face conveys Koenma's mix of seriousness and mischief, with sharply defined eyes and a tiny, determined pout. His staff-like pacifier is subtly sculpted, and the translucent base suggests a magical aura around him. The sculpt captures the contrast of his childlike frame and royal authority, with attention to the flowing folds of robes, the delicate texture on his boots, and the confident stance that hints at both shrewd intellect and occasional impatience. The paintwork emphasizes shading on robes and metallic accents to bring depth to the piece.

Koenma, the crown prince of the Demon World, travels a thin line between childlike curiosity and ruthless court politics. In Yu Yu Hakusho, he often acts as a reluctant ally or comic foil to Genkai and the human spirit detective team, using his pacifier as a symbol of power and a reminder of his responsibilities. Though young, Koenma's mind is calculating, and he wields authority with growing confidence, sometimes underestimating humans but occasionally showing surprising wisdom. His interactions reveal a prince torn between duty to his realm and friendships formed with humans, exorcists, and rivals, shaping a surprising arc of growth across the series.
