Louis (Yuriko Yoshiko), a 19-year-old girl who roams the streets of Shibuya in Tokyo, is so desperate about life that she meets a punk youth Amma (Gao Liang Jianwu) in a disco one day. Amma piercing, tattooing, tongue separation, stylish avant-garde. Under Amma's introduction, Louis was interested in snake tongue. Together, they went to the shop of tattoo artist A Chai (ARATA). The pain of wearing nails and tattoos made Louis feel more enjoyable than ever before, while the bisexual and sadistic Ah Chai was also fascinated by the petite woman. Unlike the cold and even some gloomy Ah Chai, Ama is scary on the outside, but gentle on the inside. He loved Louis so much that he even got into a fight with the underworld over the woman he loved, which foreshadowed his tragedy.
