Angel in September.

One day, Hitomi observes her classmate Eriko stealing lipstick in a drugstore and follows her home. The two young women get to know and love each other. While the withdrawn Hitomi believes herself and Eriko to be reincarnations of angel warriors who once fought demon armies, her emancipated and apathetic friend wanders through life between sex contacts with older men and fear of falling into a boring bourgeois existence. The different futures of the two soon lead to tensions.
