Reception.
The characters of Vanitas, Noé and, Jeanne were popular in Anitrendz, with Vanitas and Jeanne being nominated in the couple category. The handling of vampirism between Jeanne and Vanitas as well as Dominique and Noé was listed by Caitlin Moore from "Anime News Network" as the best moment in anime, due to the amount of sex appeal they portray directly. Vanitas changing from fighting Jeanne into forcing a kiss with her was criticized for failing to reach comedy in the place of a seemingly scary scene, due to the discomfort he causes for the woman he suddenly announces his unconditional love to, whereas Dominique objectifies Noe in an uncomfortable way. "El Palomitron" suggested that while there is no boys' love between the two leads due to the focus on other more explored relationships, El Palomitrón still found Vanitas and Noe's connection deep and comparable to the one the former shares with Jeanne, as a result of the themes each share.
