Chen is portrayed in a playful, cat-like stance that captures her mischievous charm while staying true to the Touhou character. The Masanaga ver. version emphasizes delicate sculpted details, from the flutter of her hair to the subtle bloom of her ribbon bows. Her neko ears are perched atop her head, lined with fine texture that catches the light. A flowing dress blends gradient purples with white trims, accented by a small gold bell at the collar and ribbon fastenings. The figure sits on a clear base with gentle scenic elements, such as floating petals and a tiny tea cup, hinting at her shrine-side mischief. The paintwork features soft shading in the folds and shadows, bringing depth to the pleats and accessories. Overall, the composition conveys charm, curiosity, and a hint of whimsy.
