Hiroki returned to his theme of the emotional and sexual lives of young adults in modern urban Japan in his June 1996 film "Midori" about a high-school girl pretending to be ill in order to see her boyfriend. His 2000 work "Tokyo Trash Baby" is an understated look at a lonely woman who goes through the garbage of the neighbor she is obsessed with looking for mementos. His other film in 2000 had a very different theme; the erotic comic drama "I Am an S&M Writer", with a screenplay by Hiroki's former "pink film" colleague Hitoshi Ishikawa, is based on a possibly partly autobiographical novel by celebrated S&M writer Oniroku Dan.
