This Reisen Udongein Inaba SD figure is rendered in a playful super-deformed style, emphasizing kawaii charm while preserving recognisable features. The sculpt features an oversized head and compact body with well-balanced weight to allow stable posing. The soft hair flows around her shoulders, with delicate strands and subtle shading that gives depth to the pale pinkish hair and her long rabbit ears. She wears her signature attire translated into a compact silhouette, including a frilled collar, a short dress in cool purples and blues, and tiny accessories that catch light in a glossy finish. Her face is tuned for expression, with bright eyes and a restrained smile that hints at her calm, calculating nature. The paintwork is crisp, with clean linework, precise shading, and gentle highlights on her skin, eyes, and clothing, all resting on a reliable stand that complements the SD scale.

Reisen Udongein Inaba is a Moon Rabbit from the Lunarian world. She was banished to Earth for reasons tied to Lunarian politics, and found refuge at the mysterious mansion Eientei, where she serves as Eirin Yagokoro's assistant and an adept guard. Her primary ability is psychic perception and illusion creation, which she uses to probe memories, influence feelings, and momentarily disorient foes. Despite a wary, quiet demeanor, Reisen is loyal to her companions and the people she protects, forming bonds with visitors who show kindness. This backstory informs her appearances in the Touhou realm, where she remains a calm, observant presence in any scene.
