Exxegran Giri is a senior commander in the United Nations Spacy military forces, holding a high-ranking position where he oversees strategic operations and personnel during the conflict against the Marduk alien threat. His leadership responsibilities include managing fleet deployments and coordinating defensive actions against extraterrestrial incursions into the solar system.

Personality-wise, Giri possesses a fundamentally noble spirit and principled command approach. This disposition leads him to frequently disagree with decisions from military superiors and governmental authorities. He recognizes institutional complacency within the administration, understanding that prolonged peace has eroded operational readiness and strategic vigilance. This perspective aligns him with subordinate officers sharing similar concerns about deteriorating military effectiveness, including ace pilot Silvie Gena.

His relationships with junior officers, particularly members of the Faerie Squadron like Silvie Gena and her teammates, reflect a mentorship dynamic. They regard him as a father figure due to his approachable demeanor and supportive leadership style. Their professional association becomes misinterpreted publicly when journalist Hibiki Kanzaki's sensationalized exposé mistakenly portrays their interactions as romantic, creating unintended complications despite the actual nature of their connection.

During the Marduk invasion, Giri participates in critical command decisions while continuing to voice dissent against flawed strategies. He supports the reactivation of the SDF-1 Macross and coordinates defensive measures during the final assault on Earth. His operational role includes authorizing missions and resource allocation. Giri maintains a consistent command presence throughout the conflict, characterized by his integrity and institutional skepticism.
