Lieutenant Kurtz commands the Bloodhound Squadron, an elite combat unit of the Aphrodian Freedom Force. His task involves recruiting civilians possessing specialized skills into the military resistance after Ishtar's invasion of Aphrodia. Recognizing Hiro Seno's exceptional monobike handling during a civilian attack on Ishtar tanks, Kurtz forcibly enlists Hiro's entire team.

He employs calculating manipulation to secure Hiro's cooperation, challenging him to a high-stakes monobike race across a ravine. After defeating Hiro despite granting a head start, Kurtz bargains freedom for Hiro's teammates in exchange for Hiro's exclusive service to the Bloodhound Squadron. This highlights Kurtz's strategic assessment of talent and willingness to leverage personal animosities for military gain.

Kurtz's leadership prioritizes mission success over individual survival, openly telling superiors his soldiers and equipment are expendable assets. This pragmatic battlefield mentality drives his command during the surprise assault on Io City, where he attacks Ishtar's occupying forces despite high casualty risks. Kurtz sustains injuries yet continues directing the offensive.

An ongoing rivalry defines Kurtz's relationship with Hiro, initially viewing him as a rebellious nuisance. This evolves into mutual professional respect after Hiro destroys General Donner's tank during Io's liberation. Resolving his animosity, Kurtz gifts Hiro his personal monobike in recognition of the combat contribution.

Visually, Kurtz is marked by his consistent reflective sunglasses and military regalia. His design and tactical ruthlessness position him as a narrative counterpart to archetypes like Char Aznable from the Gundam franchise, emphasizing tactical brilliance and morally ambiguous leadership methods. His characterization remains confined to his operational role during the Venus conflict.
