Airi Tachibana. 35 years old, single. A clerk at Yamashiro Tech, a mid-sized machinery manufacturer. She joined the company after high school and has worked there for 16 years. While no one notices her contributions, she effectively supports management strategy and handles overall company operations and critical decisions in place of the incompetent executive directors. She always has a fresh smile and is very sociable, so she gets invited out by men fairly often, but she is strictly chaste and has zero sexual experience. She is troubled by the sexual harassment from a managing director who is incompetent at work but constantly brings her trouble. Lately, she has been feeling a sudden sense of loneliness.
