Six people caught up in the Tokyo sex trade cross paths in the same streets. A scout working near a department store approaches a young woman and sets her on the road to porn work.

In the neighborhood lives a karaoke box attendant who cannot refuse anyone and who pictures himself an agent of the Galactic Forces, fighting yakuza and schoolgirls who take money from older men through karaoke affairs.
