Dia Kurosawa from Love Live! Sunshine!! is depicted in the Happy Party Train themed pose from the FuRyu Super Special Series. She stands in a confident, dynamic stance with one hand on her hip and the other raised as if guiding a joyful parade, capturing her poised yet lively personality. Her outfit blends a refined idol uniform with festive, train-inspired details: layered frills, sharp lines, metallic accents, and a ribbon that marks her status as a center performer. The color palette mixes navy, teal, and pastel highlights, enhanced by careful shading to reveal folds and textures in the cloth. The base resembles a stylized train car with decorative flags, while the sculpt emphasizes flowing hair, crisp edges, and glossy surfaces for a premium display.
