The audience is mostly Japanese-speaking listeners who follow vocaloid music, with an estimated split across age groups and a majority based in Japan. Viewers tend to watch for the next release, ask for instrumentals and read the songwriting notes. The channel has no sponsorship history found in its recent uploads.

Sponsored integrations would cost about $1,000 to $1,600 per video based on a median of 46,000 views, roughly $20 to $35 CPM.
