Splatter: Naked Blood (ネケッドブラーッド女虐, 女虐: NAKED BLOOD, Naked Blood: Megyaku), literally, Naked Blood: Mischief, is a 1996 Japanese horror film directed by Hisayasu Satō. It is a remake of Satō's 1987 film, Genuine Rape (暴行本番, Boko honban), and, according to AllMovie, "contains one of the most appalling scenes in Japanese horror." The film is not pornographic and contains only a mild sex scene near the end of the film.

A scientist named Eiji has developed a new chemical called "MySon" that can turn pain into pleasure and also drastically increases the pain threshold of those who receive the drug, causing them to become immune to pain. He decides to put three girls who attend a different experiment held by Eiji's mother—this experiment involving a clinical trial of a soon-to-be-released contraceptive—to the test. Meanwhile, Eiji has a crush on one of the girls, Rika. MySon influences the girls gradually, and Eiji discovers that his experiment is going horribly wrong when he finds out the drug results in too many endorphines being produced in the bodies of the people who take it when they become injured, causing them to inflict greater and greater harm on themselves to experience the same amount of pleasure. Nevertheless, Eiji continues with the experiment to observe what happens next.
