Living in an internet cafe in Kabukicho and making a living as a prostitute (15,000 yen per session), Kizumi has no dreams or hopes for life and is just drifting along. However, after hearing from her fellow prostitutes that "manga artists make a good living," she begins to struggle to escape her miserable life by drawing manga, using the pillow talk of her clients and the vast collection of manga in the internet cafe as inspiration.
