In the near future, it's possible to determine one's aptitude for a career through genetics. Betsuyaku Saika (PN: Betsusai), a 30-something aspiring manga artist, was once diagnosed with an aptitude for "manga artist" but her talent hasn't blossomed. She takes a re-examination but... Turns out the previous test had a minor filter and her true calling was actually “self-pleasure artist”! Confused, Saika tries drawing self-pleasure content and it goes viral. She becomes utterly hooked on satisfying her need for validation through self-pleasure art. Eventually, she goes to a hotel with her sole long-time fan under the pretense of “collecting reference material for an off-camera book” but... What fate awaits her?!
