St. Louis is presented in a bunny Ver design that blends the gentle charm of Azur Lane with playful heroics. The figure stands at a poised angle that suggests both grace and readiness, with her long hair cascading, bunny ears perched atop her head, and a refined naval uniform adapted into a playful bunny outfit. The sculpt by Norimiki Ujikawa (Dragon Craft) captures fine lines on her face, the subtle shading across the costume, and the delicate texture of ATBC-PVC and ABS materials. Painted details by yozakura bring depth to her epaulettes, ribbons, and accessories, while FREEing's signature 1/4 scale yields a formidable presence in any display. Pre-painted finish ensures instant display right out of the box.

As a character in Azur Lane, St. Louis represents a disciplined yet warm personality from the Royal Navy ship line, known for her quiet intellect and steady leadership. Within the game's lore she is a trusted advisor, frequently aiding younger hulls during campaigns and events, while maintaining a polite, dignified demeanor. The Bunny Ver variant adds a touch of whimsy, softening her stern aura with a playful costume that invites fans to connect with her on a more personal level. This collaboration—Dragon Craft with Norimiki Ujikawa, and paint work by yozakura—preserves her archetype while highlighting her adaptability and enduring charm across the fleet's adventures.
