She used to work for Telenet Japan and Riot, but many people who worked for these two companies left, and along with Naruke, later started working for Media.Vision. She has composed music for games outside of the Wild ARMs series, such as Psycho Dream on the Super Famicom and the Tenshi no Uta series on the PC Engine. While it was speculated that Naruke composed under the psudonym "Hassy" for the @MIDI albums, the composer herself has stated that Hassy is a separate individual (Hiroya Hatsushiba).
She has made a number of songs for Media.Vision's Wild ARMs series. Occasionally, the main theme and ending theme of the Wild ARMs songs will contain lyrics, formerly being sang by Machiko Watanabe and Kaori Asoh. Most recently, for the tenth anniversary, a new vocalist has been introduced, Nana Mizuki. Her compositions in the Wild ARMs series include her signature whistling parts, whistled by Naoki Takao. Naruke has composed more than 400 songs for the Wild ARMs series. However, during the development of Wild ARMs: The 4th Detonator, Naruke fell ill, marking the first time in the Wild ARMs series that she did not compose the entire soundtrack.
In an interview for Wild ARMs: Piece of Tears, Naruke revealed items which she values, including her keyboard and rhythm machine, a pamphlet of Jerry Goldsmith, a figure of Kurokishi from "Gingaman", an original score of Bach, and a memorial vinyl disc.
