Stratosphere girl (2004)

Angela is a French art student living in Germany who loves to draw comics and creates elaborate tales drawn in a soft and romantic style. One night, Angela meets Yamamoto, a club DJ from Japan, who invites her to come to Tokyo with him. Infatuated with Yamamoto, Angela impulsively agrees, and is soon sharing an apartment with a handful of Western expatriates who work at a nightclub where Japanese businessmen drink, sing karaoke, and date the "hostesses" for a fee.
