The Souei figure captures the essence of the character with a poised, ninja-inspired silhouette and a careful attention to detail. Painted in deep navy and charcoal tones, it highlights crisp edgework on the cloak, layered fabric folds, and subtle metallic accents that suggest armor and accessories. The sculpt emphasizes a calm, controlled stance, with one hand positioned as if ready to draw a blade or cast a quick illusion. The overall finish is smooth with a matte sheen on the cloth and a gloss on the eyes, conveying a sense of mystery and precision.
