Shaya Thoov commands the Emaan trading vessel *Glomar*, responsible for navigation, commerce, and tactical decisions in conflict. As a member of the ruling Tobu clan among the nomadic Emaan traders, she strictly observes Emaan cultural practices, including distinct customs around communal bathing and fertility cycles. Her initial mission is transporting Kei Katsuragi, a "Tokuiten" (dimensional singularity), to the Emaan homeland under Tobu orders.

Her leadership faces a critical test when the Tobu clan attempts to forcibly brainwash Kei for political gain. Defying her own clan, Shaya rescues Kei, transforming the *Glomar* into a fugitive vessel hunted by Tobu military forces led by her sister, Maneesha. This act fractures her familial loyalty as she prioritizes restoring dimensional stability over clan allegiance.

Facing worsening dimensional instability on Earth, Shaya devises a plan to reach the orbital elevator—the collapse's epicenter—deep within hostile Mu territory. She brokers a temporary alliance with former enemies, the Chiram army, acknowledging the necessity of combined strength against Mu technology and escalating environmental disasters. This strategic shift highlights her adaptability and commitment to planetary restoration. In the final assault, she coordinates joint forces attacking the orbital elevator, enabling Kei and Olson to reach the dimensional bomb at its apex.

Her appearance and role in the sequel OVA "Orguss 02" or other spin-off media remain undocumented.
