The sculpt captures her slender silhouette, with long flowing hair swept to one side and strands curling around her shoulders. She wears an elaborate dress that combines gothic and fantasy elements—ruffled lace, layered skirts, and subtle ribbon accents. The paintwork emphasizes contrast between pale skin and dark garments, with jewel tones accenting the eyes and accessories. The base features dreamlike motifs and soft fog effects to evoke the Nightmares realm. The figure is crafted in PVC and ABS, presenting crisp details, smooth surfaces, and a balanced, dynamic stance. It conveys motion and haunting beauty.
