Ezra, born Isora Daiba, holds a senior position as a military secretary in the Gaia Sanction, an authoritarian regime regulating access to Earth. He is the elder brother of Yama (renamed Logan in English versions) and politically wed to Nami, their union devoid of affection but securing her life-sustaining medical care. A childhood accident in their shared Martian greenhouse left Ezra paralyzed, dependent on a hoverchair, and Nami reliant on life support. He harbors lifelong bitterness toward Yama, whom he holds responsible for the tragedy, manipulating his brother into infiltrating the Arcadia crew under the pretense of atonement. Cynical and manipulative, Ezra weaponizes emotional cruelty, exploiting weaknesses to dominate others. While publicly championing the Gaia Sanction’s mission to safeguard Earth, his choices are fueled by ambition and a thirst for control. He privately acknowledges the organization’s corruption, particularly its plot to annihilate Earth with the Jovian Blaster. This spurs him to redirect the superweapon’s path—saving the planet while framing the act as a tribute to Nami, whose unreciprocated affection he clings to. A master tactician, Ezra deploys holographic decoys and commands the battleship Oceanus, outmaneuvering adversaries with strategic precision. Yet his vendetta against Yama and Captain Harlock erodes his judgment, culminating in reckless assaults. In a final confrontation aboard the Arcadia, he fatally wounds Yama before being killed by Harlock. With his last breath, he claims devotion to Nami’s memory, though his legacy balances between enabling the Gaia Sanction’s tyranny and his paradoxical sacrifice to halt Earth’s destruction. Rising through the regime’s ranks through a blend of ideological conviction and opportunism, Ezra’s trajectory was irrevocably altered by the greenhouse accident. The event solidified his abusive control over Yama and his calculated marriage to Nami, ensuring her survival while deepening his bitterness. His fatal intervention against the Jovian Blaster introduces unresolved complexity, hinting at buried loyalty to Earth beneath layers of self-interest and vengeance.
