Last Origin - Labiata Prototype in Mizugi Ver. is presented as a high-detail 1/7 scale figure designed to capture the sleek silhouette of the prototype unit. The figure stands in a dynamic pose with a lean, athletic build, one knee slightly bent, and a confident gaze that hints at its tactical precision. She wears a two-piece Mizugi swimsuit featuring a deep navy base with aqua accents and chrome-like armor plating on the shoulders, forearms, and thighs. The suit is textured to show fabric weave and subtle seams, while the armor pieces have metallic sheen and fine panel lines. The base evokes a water scene with translucent waves and soft spray effects, and there are subtle shading gradients on skin, hair, and armor to enhance depth. The finish blends glossy swimsuit, matte armor, and polished chrome to create a premium display piece ideal for collectors.

Within the Last Origin universe, Labiata Prototype is introduced as a test model developed by the research division to explore autonomous combat capabilities and compatibility with cybernetic upgrades. She embodies a blend of elegance and brutal efficiency, designed to operate in both terrestrial and aquatic environments thanks to the Mizugi variant's hydrodynamic chassis. Her backstory centers on field trials where she must adapt to shifting threats, analyze data in real time, and maintain loyalty protocols even under extreme stress. As a character, she is curious and observant, yet remains cool under pressure, often forming trust with pilots and fellow units during joint exercises. The figure captures her poised, confident demeanor, agile movement, and a serialized identification code along her armor, symbolizing a unit that is ready for deployment and evolving AI consciousness.
