Faust is a young researcher initially affiliated with Teito’s pharmaceutical division, later unveiled as the founder and president of Metal Technica—an organization dedicated to studying the "Light" and advancing "Soul Technology." His work focuses on vaccine development, including one targeting luminosis, though the specifics of his research remain closely guarded. Before founding Metal Technica, he directed a laboratory where he experimented with soul energy, pursuing humanity’s salvation even at the cost of substantial sacrifices.

He exhibits a direct, analytical demeanor, often speaking with grave seriousness and grounding his perspective in realism. His personality reflects unwavering dedication to scientific progress, prioritizing it above personal connections. Interactions with figures like Leocadio Wöhler and Conrad Wisdom are marked by professional detachment; he shares minimal details about his work while acknowledging its potential impact on mankind.

Faust engineered the mascot "Magatsu" from an enigmatic egg, assigning it the full name "Michael Galgali Zarathustra" via randomized selection before abbreviating it for practicality. Though Magatsu serves as Metal Technica’s public symbol, Faust’s personal involvement in its comedic promotional campaigns remains unspecified.

Metal Technica operates as both a research hub and corporate entity, testing soul energy applications through ethically ambiguous methodologies. Faust’s motivations blend altruistic goals with a willingness to employ morally complex tactics, positioning him as a pragmatic visionary driven by scientific advancement.

No additional details regarding his portrayal in other official media are documented.
