Kinshi-chou Night Survive

This is Kinshicho in Sumida-ku, Tokyo. Konatsu, a loli-looking young woman, comes to Tokyo from Akita, hoping to become a cabaret club hostess. But she is rejected by one night club after another. She wanders into a dentist's office and runs into an old man who used to be her childhood dentist from back home. When she put herself 3-million yen in debt due to an accident, she begins working for the old dentist as an assistant in his late-night clinic. Even though Konatsu has a steady new job as a dental assistant, she is still struggling to hold on to her dream of becoming a cabaret girl. Let's get dental! (Source: Kodansha, translated)
