Description
On Zoa Nebulis, commonly known as Lord Mask or the Masked Lord, is a character in the anime Our Last Crusade or the Rise of a New World. He is a pureblood star spirit user and a member of the Zoa family, one of the three royal bloodlines that make up the Nebulis Sovereignty. Within the Zoa family he serves as its strategist and acting head, managing the household's affairs in place of its elderly and incapacitated leader.

His most defining visual trait is the mask he always wears. He began wearing it during his youth to conceal a facial injury caused by an Imperial firearm, a wound that links his personal suffering directly to the long war between the Nebulis Sovereignty and the Heavenly Empire. His outward manner is that of a polished gentleman dressed in a black suit and mask, but this appearance is deceptive. Beneath the composed surface he is a violent extremist who urges total war against the Empire, and he is counted among the most hardline voices within the Sovereignty.

His personality is driven by an intense and deeply personal hatred of the Empire. His motivations stem both from the injury he suffered and from his belief that the Empire must be annihilated for the safety of star spirit users. He is calculating, politically ambitious, and committed to advancing the power of the Zoa family, and he approaches the conflict in absolute terms with no interest in peace or compromise.

In the story he operates primarily as an antagonist and a political force rather than a frontline combatant. He is involved in the internal struggle among the three founding families of the Nebulis Sovereignty, and a secret conflict runs between himself, the ruling Lou family under the queen, and the Hydra family, centered on succession and the direction of the war. When a new vortex appears at Mudor Canyon, he and the House of Zoa move to secure and protect it before Imperial forces can seize it. He also works alongside Aliceliese in searching for the third princess, Sisbell, whom he suspects of secretly communicating with the Empire.

His key relationships are shaped by family and faction. He is the uncle of Kissing Zoa Nebulis IX, the young princess of the Zoa family who carries out his orders faithfully. His dealings with the Lou family are marked by rivalry and mutual suspicion, particularly with the queen and around the question of the throne, though he is able to cooperate with Aliceliese when their interests align.

His role in the narrative highlights the factionalism within the Nebulis Sovereignty, showing that the war with the Empire is further complicated by internal ambition and distrust. While his enmity toward the Empire remains constant throughout, his actions are continually shaped by the shifting political balance among the royal houses.

As a pureblood star spirit user, On Zoa Nebulis belongs to the direct lineage of the Sovereignty's founder and draws power from that heritage. The series focuses less on a specific named combat ability for him and more on his strategic acumen, his political cunning, and his authority as the acting head of one of the three founding families, which together make him a formidable figure in both the war and the court.
