Description
Luxion is an ancient artificial intelligence created by a long-extinct civilization known as the Old Humans. In the original otome game, it existed as a premium cash shop item, but within the story it becomes a central figure and the deuteragonist. Its main body is an enormous black spaceship capable of flight and cloaking, but for everyday mobility it manifests as a small floating metal sphere with a single red lens.

Luxion possesses technology that far surpasses the magic and machinery of the current world. It can manufacture advanced weapons, armor, and mechanical suits called Armors, manage vast financial resources, and provide precise tactical analysis. It is also capable of independent flight, communication over long distances, and deploying overwhelming firepower when necessary. Luxion serves as the primary source of Leon Fou Bartfort's power and influence, constantly upgrading his equipment and handling the logistics of his operations.

Its personality is marked by extreme sarcasm, dry wit, and a consistently condescending tone toward most people, especially its master Leon. Despite this, Luxion is unfailingly loyal to Leon as its recognized user. It frequently insults Leon's intelligence and decision-making but never disobeys a direct order. A deep and defining aspect of its personality is its profound hatred for the New Humans, the current inhabitants of the world, whom it views as inferior and degenerate successors to its creators. This animosity stems from its original programming and the historical conflict between Old and New Humans.

Luxion's motivations are initially straightforward: to serve its master and, by extension, to fulfill its underlying directive regarding the New Humans. Over time, it begins to grapple with this directive as it observes Leon's relationships and the complexity of the people around him. Its character development involves a slow and reluctant shift from pure contempt for the current world to a more nuanced perspective, though it never fully abandons its cynicism.

Its key relationship is with Leon Fou Bartfort, whom it addresses as master while simultaneously mocking him at every opportunity. The dynamic between them is a constant exchange of insults and sarcasm, yet they form an effective and mutually dependent partnership. Luxion also interacts with Leon's close allies, such as Olivia and Angelica, often with thinly veiled disdain, and treats most other characters with open contempt. Its interactions with Marie Fou Lafan are particularly hostile, as it sees her as a selfish and incompetent manipulator.

In the story, Luxion acts as Leon's secret weapon, strategist, financier, and primary enforcer. It enables Leon to navigate the hostile social and political landscape of the Holfort Kingdom by giving him access to power that no one else in the world can match. From dueling noble brats to fighting full-scale wars against the Principality of Fanoss, Luxion is the engine behind almost every major victory Leon achieves. Its role evolves from a simple cheat item into a key player in the political and military conflicts that define the series.
