Strarf Bis presents a striking silhouette with a demon-themed armor set that blends sleek, angular plates with jagged crimson accents. The MMS Type Devil configuration features horn-like protrusions on the helm, sharp edge details along the chest piece, and layered skirts that evoke motion even at rest. The figure's joints are engineered for dynamic posing, allowing high-action stances and expressive display angles. Textured surfaces simulate worn, battle-ready metal, while glossy paint highlights the weapon housings and energy cores.

Within the Busou Shinki universe, Strarf Bis is depicted as a commissioned guardian forged from the Devil’s lineage, assigned to protect ancient data cores and guardian artifacts. Her design fuses agile combat capability with a ceremonial aura, making her equally at home on the battlefield and in the display case. She squads with other Strarf units, responding to threats from rival factions, balancing ruthless efficiency with a stubborn loyalty to her master. Her storyline explores themes of duty, identity, and the cost of power, as battles reveal the true strength of a Shinki forged for both honor and conquest.
