- Her real name, Lena, appears to be a reference to René-Maurice Gattefossé, who pioneered the term "aromatherapy" through his 1937 book Aromathérapie: Les Huiles Essentielles, Hormones Végétales.
- Perfumer's real name was originally Lyra, but this was changed when Arknights was released.
- Perfumer has the traits of a Fennec fox (Vulpes zerda). One can be seen in her Elite 2 artwork as well as her outfits.
- Perfumer is the only operator who calls the Doctor with -kun (君/くん) honorific in her voice line. This implies that Perfumer is rather close to the Doctor themselves.
