This 1/7 scale figure captures Nagatsuka Saki in the Shiro Usagi-san variant with meticulous attention to detail. The character is posed dynamically, mid-step as if she is skipping forward with a playful wink. She wears a white bunny-themed outfit that blends a cute schoolgirl silhouette with fantasy elements: a frilly dress with lace trim, a fluffy tail, and slender bunny ears perched atop a headpiece. Soft shading highlights the sculpted folds of the fabric, the sheen of the PVC surface, and the delicate line work on the tights and boots. The base features hare-inspired motifs, pastel accents, and subtle weathering to imply movement. The long strands of hair cascade around the shoulders, catching light in carefully placed highlights. The Shiro Usagi-san design emphasizes charm, whimsy, and a sense of motion, typical of PLUM's craftsmanship with clean lines and tight paint control.
