Lemrina Vers Allusia is a princess of the Vers Empire and the half-sister of Empress Asseylum Vers Allusia, sharing the same father but having different mothers. She first appears in the second half of Aldnoah.Zero and is physically confined to a wheelchair, unable to walk. Despite her royal blood, she has always felt out of place within the imperial court and received cold treatment during her upbringing, which shapes her complex emotions and ambitions.

Lemrina is a shrewd and calculating individual who is intimately familiar with the political workings of the Vers Empire. She is a skilled actress and manipulator, habitually concealing her true nature behind a composed facade. She is keenly aware that her primary value to the empire lies in her ability to activate Aldnoah drives, a power inherent to the royal bloodline, and she resents being used merely as a tool. Nevertheless, she continues to fulfill that role because it gives her a sense of usefulness and purpose.

Her motivations are driven by a deep-seated envy of her half-sister Asseylum, who possesses greater status and advantages. Lemrina secretly hates her own royal heritage and longs for recognition and agency. This emotional void leads her to befriend Slaine Troyard, who treats her as more than a tool, and she later agrees to marry him. At Slaine’s direction, she impersonates the comatose Asseylum in a public broadcast that urges the continuation of the war, a deception that only Inaho Kaizuka suspects. Throughout the story, she remains a figure who oscillates between complicity in the conflict and a desire for personal connection, gradually developing a more complex relationship with her own identity. Her most notable abilities are her political acumen, her talent for deception, and her innate capacity to operate Aldnoah technology.
