Dorlin is an old woman with gray hair and yellowish gold eyes. She wears a witch hat and a hooded robe over a suit complete with a white shirt and a tie.
Dorlin is a serious and calculating woman. Despite being a Luna Nova alumna herself, she has low opinions about the academy for its outdated ways which, as she pointed out, negatively affected magic in general. Conversely, she and her cohorts are pleasantly surprised by Akko, Lotte, and Sucy improvising the sacrifice and ultimately, freeing Vajarois from her suffering.
Dorlin is one of the special guests at the Samhain Festival. She presents the show next to Ural and Marjolaine and like her fellow guests, she finds the Samhain Festival boring. She seems to put her expectations into whether Diana deserves the surname Cavendish or not. She was amused by Akko and co.'s presentation, laughing all along at Akko's poor magic skills, and was visibly impressed when Akko managed to free Vajarois of her curse.
- Her voice actress, Eri Nakao, also voices Hannah.
