This period established a distinctive aspect of their artistic identity, earning a reputation within the industry for a particular thematic focus that became a notable hallmark of their early adult-oriented publications.

Transitioning to broader audiences, Ditama gained prominence as the illustrator for the general-audience manga series Mahoromatic (Mahoromatic: Automatic Maiden). This series served as a significant step in raising their profile in mainstream manga. Ditama is also the author of Kiss×sis, a manga that was later adapted into an anime.

The artistic identity of Bow Ditama is characterized by a style that has been noted for its incorporation of elements reminiscent of shōjo (girls') manga, which led to early speculation about the creator's gender.

Their career represents a trajectory from a highly specific niche within the adult manga market to becoming a recognized creator in general-interest manga and anime, demonstrating a versatility that includes writing, illustration, and direct animation production.
