Standing at 148 mm tall, this Seifuku ver. figure of Nagatoro Hayase captures her mischievous energy with finely detailed sculpting and careful paintwork. She wears a traditional sailor-style school uniform with neatly rendered fabric folds, a short skirt that conveys motion, and a playful pose that tilts her head forward with a teasing grin. Her hair is sculpted in dynamic strands that frame her face, and subtle shading on skin, uniform, and accessories enhances three-dimensionality. The figure sits on a simple round base that complements the pose without distraction. PVC and ABS construction ensures crisp details, solid color transitions, and a smooth finish across the whole piece.

Nagatoro Hayase is the central female character of Ijiranaide, Nagatoro-san, known for her sharp wit, playful teasing, and unexpectedly warm heart. As a high school student she delights in provoking her timid senior—often called "Senpai"—pushing him out of his comfort zone with cheeky remarks, physical antics, and competitive challenges. Beneath her teasing persona lies a perceptive and loyal friend who recognizes and encourages personal growth. Over the course of the series Nagatoro's interactions shift from outright taunting to a complicated mix of flirtation, genuine care, and vulnerability; she can be both confident and unsure, a blend that drives much of the story's emotional and comedic tension. Fans are drawn to her energetic spirit, evolving relationships, and moments of sincere empathy that reveal deeper layers beyond the mischievous exterior.
