The core premise follows a standard but highly effective trope in romantic and adult manga: an introverted or ordinary protagonist whose personal space is suddenly invaded by a vibrant, fashionable "gyaru" (gal).
The manga was first published by the artist Manno under the circle name Amagami Honpo at Comiket 101 in December 2022. The English title, Drop-in Gyaru Lets Me Use Her Pussy , has been officially released in digital format by Irodori Comics.
