exemplified by the fact her boy's heart gives her physical strength. Mautner also found "some" sexism in the work, given as an example the fact she loses her swordsmanship ability when she is without her boy's heart. Drazen and Mautner stressed that the manga had broken with some gender expectations but did not abandon them, as Sapphire marries Franz in the end. Power stated that by this attitude Sapphire shows "her true happiness comes from being in a traditional female role." For Paul Gravett, it demonstrated she "was no feminist rebel after all" and he wrote in Manga: Sixty Years of Japanese Comics that Tezuka "created an exquisite world of indecision." Power concluded that "The image of Sapphire must have sent complex, if not conflicting, messages" to readers. This conflicts led Brophy to say "It may be more accurate to depict her characterization as schizophrenic rather than androgynous". Snow Wildsmith of ICv2 described the series as having "younger characters [who] do not want to stick to the roles their parents proscribed for them and most of the women are tired of being told that they are the lesser sex." Mautner wrote that "if there's a central theme in Princess Knight, however, it's not that of sex roles but of parental expectations and filial duty". Drazen also exposed that the series deals with "another classically Japanese pair of opposites: duty and desire." Drazen said "she doesn't resent her duty" of having to be a boy and have fun with it, but that "only in private does she live out her feminine desires." Mautner expressed a similar view, affirming that even if she likes to be a boy "possesses a strong desire to indulge her female side."
