Lu Sheng Mao, hailing from the corrupted Shanghai server, operated as the Gunner of the Garuda mecha unit. His father, CEO of a prominent investment firm, channeled substantial resources into iAL—a pivotal entity enmeshed in the series’ core conflict. Initially skeptical of Kyo Sogoru’s capabilities, Lu Sheng gradually gained admiration for Kyo’s unwavering dedication to shielding others, acknowledging both his sincerity and evolution as a pilot. Known for his calm demeanor, Lu Sheng maintained guarded skepticism toward Shizuno Misaki’s concealed intel on the Gards-orm threat. His dynamic with the devoted twin Wizards Jen May-Yu and Jen May-Yen reinforced his authoritative presence within Garuda. When the Shanghai server faced annihilation, he partnered with Kyo and Shizuno in desperate salvage operations, a mission marred by devastating casualties, including the loss of the Zegapain Caladrius. A defining turn in his journey came when he openly confessed romantic feelings for Kyo, unveiling hidden emotional layers beneath his stoic exterior. This vulnerability, paired with their deepening camaraderie, contrasted sharply with the relentless battles against existential annihilation. Expanding his role in subsequent narratives like *Zegapain STA*, Lu Sheng became integral to the "Olta Moda Arc," his endeavors entangled with high-stakes plot threads such as backup servers and legacy data systems. His persistent franchise presence underscored an unyielding resolve to defend both the fabricated Maihama domain and humanity’s fractured remnants in reality.
