30-year-old Marina Nishi, an active flight attendant, makes her AV debut! She has a beautiful appearance and has lived a serious life with a straight back, but that is just her public face. Perhaps because of the stress that accumulates from playing the role of a saint, her libido has been growing stronger year after year. She came to challenge AV, which she was honestly interested in, shedding the mask of a flight attendant. She reveals her model-like 8-head body in front of the camera and, amidst a mix of excitement and anxiety, she releases her own desires! This is a documentary of one woman's AV debut.
