It begins with the titular "A Knife-Edge Girl" a story about two friends with completely different approaches to life. Also includes "Graffiti," in which two women who use the same desk at different times of the day communicate in drawings on the desk top. When they finally meet in real life - purely by accident - the attraction is instant on Kana's side…and maybe not on Rise's. Or maybe, it is. In "Torte Fromage" Miwa's boring OL life is suddenly thrown into glamour and excitement when she meets avant garde actress Nakae-san.
