I am looking for the name of a film I saw around 2005, and probably appeared not much earlier.
The main character is a (possibly scandinavian) girl. At her high schools graduation ceremony, she meets a Japanese boy, and spontaneously decides to move to Japan. There she works in a night club. In her free time she draws comics, which are sometimes cut into the live-action film itself. The first part of the film deals with her everyday life, tensions between coworkers. At the middle of the film she says as a narrator that the main character needs a main antagonist, and it is not always clear who the antagonist will be. Then the main antagonist is introduced: A patron of the night club, who likes to dress up the girls, e.g. in bavarian style. One of her coworkers disappears, and there are hints that this guy is connected to this crime. She gets the opportunity to visit him in his house, where it turns out that the missing girl got hurt (possibly with a scissor) during a dispute with two other girls, and is now recovering in his house. She is caught sneaking around, but instead of getting punished she gets an offer to sell her comic as a film script. These final scenes are shown only in her comic pictures. The film then cuts without explanation to a final shot and shows her back home in the garden behind her parents house.
The film might have been a Swedish production. I think the film referred to an actual case of a foreign girl disappearing in Japan.
