Roza Plevitskaya, a lieutenant in the Air Force and astronaut candidate, is renowned as the "White Rose of Sunglade," a title earned during her decorated tenure as an ace pilot. Driven by a fiercely competitive spirit and rigorous discipline, she commands authority among her peers, adopting a stern demeanor that surfaces most sharply in exchanges with Lev Leps, whose reserved disposition and disciplinary history clash with her exacting standards.

Her leadership within the candidate cohort stems from her combat-tested expertise, though her relentless pursuit of superiority often leads to dismissiveness toward those she deems unworthy of the program’s demands. This tension evolves after Lev’s unexpected ascension as the first human cosmonaut, compelling her to reluctantly reassess her judgments and acknowledge his resilience.

Roza’s interactions remain anchored in the high-stakes arena of astronaut selection, emphasizing the program’s competitive ethos. Her narrative underscores the friction between personal ambition and collective mission, mirroring the broader ideological struggles within the space initiative. Adaptations uniformly preserve her role, maintaining her as a steadfast emblem of rivalry, discipline, and the unyielding pressures of extraterrestrial aspiration.
