Izayoi Sakuya is depicted in a refined maid uniform inspired by the Touhou Project aesthetic. The figure presents long silver hair cascading in subtle strands, with delicate shading that suggests movement and light reflection. She wears a black dress with a crisp white apron, ornate lace trim, and a bold crimson bow at her collar. Her pose balances elegance with readiness, one hand lightly lifting her skirt while the other rests near her waist, ready to summon her knives. Accessories include perfectly sculpted blades tucked at the sides and a detailed base evoking a clockwork motif that complements her time manipulation theme.

Izayoi Sakuya, originally a human girl brought into the Scarlet Devil Mansion, serves as the mansion's head maid and loyal attendant to Remilia Scarlet.

She maintains calm, precise manners and a protective devotion to her mistress, often planning with meticulous care to safeguard the mansion from intruders or threats. Despite her polished exterior, Sakuya's resolve reflects a depth of responsibility and sacrifice, making her a memorable figure within the series.
