The movie "Culling Compensation Dating Girls" is adapted from a comic with the theme of assistance and communication, telling the story of a middle-aged male and a female high school student carrying out a fierce killing. The film has been producing a series of trilogy since 2001, bringing the theme of "Aid Social Fighting Movement" (Aid Social Fighting Movement) to the screen. Kosuke Suzuki, who directed the first three films, once again served as director, and Akino Yuni played the role of a high school girl, challenging intense scenes including violent scenes. The film reveals the secrets behind the seemingly ordinary life of a high school girl, Aimi, who trades in aid to fulfill her dreams

In the film, behind the ordinary life of Aimi, a female high school student, lies the other side of her earning money by helping her socialize. Meanwhile, policeman Kumakiri, with a tragic past, oversees the release of three former sex offenders, Kunimoto, Kiguchi, and Oshima. However, these three people, out of Xiong Qier's sight, used social assistance to attract female high school students, and posted their situation on the Internet, forming the so-called "social assistance extermination movement". They keep repeating this behavior, putting high school girls in danger.
