Noel is a maid serving at the Lou Erz Mansion, the estate of the Lou family in the Nebulis Sovereignty. She is the oldest of the five maids who oversee the household, working alongside maids such as Yumilecia. During the events of the second season, after the Night of the Witch Hunt, Noel and her fellow maids form an alliance with Unit 907, the imperial task force led by Mismis Klass. Their cooperation is aimed at rescuing Sisbell Lou Nebulis IX, the third princess of the Sovereignty, who has been captured by the Hydra family. Noel's role is primarily as a domestic servant, but her participation in this alliance demonstrates her willingness to take action in support of her mistress and the Lou household. No further details about her personality, motivations, or any special abilities are explicitly documented in the available sources. Her development is tied to her involvement in the rescue operation, showing a shift from purely domestic duties to a more active role in the unfolding conflict.
