As anime evolved, so did the treatment of themes related to artificial intimacy. Titles like Mahoromatic, DearS, and He is My Master incorporated more overt eroticism, often featuring humanoid or subservient female characters who serve as companions, caretakers, or love interests. These characters are frequently designed to appeal to the male gaze and fanservice aesthetics, positioning them not just as story elements but as symbolic representations of idealized femininity. In many cases, these anime serve as reflections of otaku culture's engagement with moe (a feeling of affection toward cute, idealized characters) and the desire for safe, controllable intimacy.

In more explicit genres, including hentai or erotic original video animations (OVAs), the concept of sex dolls anime becomes even more direct. These works may depict android lovers, inflatable companions, or magically animated cheap sex dolls fulfilling sexual or romantic roles for the protagonists. While often dismissed as fetish content, these narratives can still offer commentary on issues such as isolation, escapism, and technological dependency. The depiction of synthetic love interests as willing, devoted, and aesthetically perfect partners underscores a tension between real-world emotional labor and fantasy fulfillment. For some viewers, these stories become a form of catharsis or wish fulfillment, particularly when social anxiety, loneliness, or lack of intimacy shape their lived experiences.
