Veuve Elizabeth, also known as Beth, is a Hungarian character affiliated with the unit LOST EDEN. Born on August 7, Elizabeth shares historical parallels with the Hungarian noblewoman Elizabeth Báthory, including the identical birthdate and approximate birth year of 1560. Elizabeth operates an apparel store named Rougelian, providing assistance to beauty seekers and demonstrating fashion design expertise through stage costumes created for the unit OZ.

Elizabeth exhibits a profound appreciation for beautiful things and commands extensive knowledge of magic, frequently serving as a reliable resource. Standing 165 cm tall with blonde shoulder-length hair and pink eyes, Elizabeth's appearance features distinctive elements like a beret and one visible eye. Pronoun usage varies across interpretations: Japanese materials occasionally employ third-person self-references as "Beth," while English localizations diverge—Funimation uses "they/them," Aniplus Asia uses "she/her," and the voice actor reportedly utilized masculine pronouns in interviews. The Japanese portrayal typically avoids explicit pronouns, contributing to ongoing fan discourse on gender representation.
