Naoko Naruse is recognized as an original creator in the anime industry, credited for her work on the original net animation series Rokurō no Dai Bōken. Her role is unique, as she exists as both a creative professional and a character within the narrative universe from which the spin-off originates.

The origin of this work lies in the anime television series Yakunara Mug Cup Mo, also known as Let's Make a Mug Too, a production that promotes the city of Tajimi in Gifu Prefecture, Japan, famous for its Mino pottery. Within this series, Naoko Naruse is a fictional character, a high school student and a member of the pottery club, who creates a small mascot character named Rokurō. This fictional creation became the basis for a real-world spin-off project. The Rokurō no Dai Bōken anime was produced as a collaboration with the DentalE dental hygiene application and premiered in the spring of 2024. In a notable meta-textual development, Naoko Naruse, the fictional character from the original series, is officially credited as the original creator for this spin-off anime.

The production staff for Rokurō no Dai Bōken includes Tsutomu Yabuki as director and Mayumi Watanabe handling character design and serving as chief animation director, with animation production by Planet Studio. The series follows the Rokurō mascot character as it assists dental professionals and provides educational information on preventing common dental diseases. This project represents a unique cross-section of the anime industry, functioning as a promotional work for regional tourism, an adaptation of an in-universe fictional element, and an educational collaboration with the healthcare sector.
