Nor Barcoff commands an experimental unit tasked with executing perilous missions in the ongoing clash between the Gilgamesh Confederation and Balarant Union. Stationed initially on Galeade, he leads a squad featuring Chirico Cuvie, Garry Godan, Glenborash Doroca Zaki, and Dare Kochak, directing complex operations ranging from covert nighttime assaults on enemy fortresses to quelling internal strife—such as halting Zaki’s attempted murder of Chirico.

Barcoff’s strategic acumen shapes missions like the infiltration of Balarant’s Manido Gorge fortress, where he divides the team into synchronized strike teams employing rockets and close combat to breach defenses. Operational flaws, including Kochak’s oversight in neutralizing threats, trigger disastrous chain reactions like structural collapses and heavy losses. Barcoff responds with strict emphasis on objective completion, sidelining personal accountability.

Beyond combat, he enforces rigorous maintenance protocols and counters external disruptions, from sabotage to mysterious attackers infiltrating their base. When a polymer ringer malfunction ignites Chirico, Barcoff maintains procedural focus, subtly acknowledging potential enemy manipulation. His squad later escapes a fuel-tank detonation through rapid improvisation, proving resilience amid chaos.

He adheres unwaveringly to hierarchy, accepting hazardous redeployments even as factions like the "Gilgamesh Purification Committee" orchestrate transport crashes. During such crises, he prioritizes system reactivation over crew conflicts, embodying a detached, mission-centric ethos. The narrative frames his leadership through immediate challenges, omitting personal history or motivations beyond operational exigencies.
