Identified as both "Shades" and Gurasan, he serves in Shield Squadron, a conventional military unit providing combat support to the Valkyries at Tateyama Air Base during operations against the Pillars. Gurasan possesses a distinct appearance: bald head, constant use of sunglasses, green shirt, black pants, and boots. His design incorporates an "Ink-Suit Actor" trope reflecting his voice performer. Wielding a Mitsubishi F-15J fighter, Gurasan operates alongside Shield Squadron members nicknamed for hairstyles. The squadron's primary role is direct combat assistance to the 909th Squadron, particularly in critical missions against the Pillars, highlighting broader military coordination beyond the Valkyries. During the large-scale assault on the Fuji Pillar, Shield Squadron engaged in defensive operations against Thor, a powerful entity emerging from the Pillar that inflicted heavy casualties. Gurasan and his squadron perished executing a covering maneuver for Valkyrie Miyako Muguruma's final attack run against Thor. This sacrifice represents a documented instance of conventional forces directly enabling Valkyrie success against overwhelming opposition. No expanded backstory, character development, or alternative appearances for Gurasan exist within the light novel spin-offs (*Rusalka*, *Sakura*) or manga adaptations (*Non-Scramble*, *Kurū no Eiyū*). His narrative presence remains confined to the anime's depiction of Shield Squadron's operational support and fate during the Fuji Pillar offensive.
