009-1 is an original manga series written by Shotaro Ishinomori. It started on August 10th, 1967 and ended on March 5th, 1970 and consisted of six volumes.
The manga series was adapted into a live-action tokusatsu show called "Flower Action 009-1" in 1969, and further adapted into an anime series that aired in late 2006.
Both the live-action and anime adaptations take considerable liberty with the source material. In "Flower Action 009-1", there is no Mylene Hoffman and the protagonists consider of a five-woman squad (Heart, Spade, Monkey, Club, and Diamond).
In the anime adaptation, the Nine Number Group is elaborated on a little more, with it being said to consist of twelve female secret agents, as opposed to the group's brief appearance in the manga where Mylene and the deceased 009-7 appeared to be the only women on the team.
The manga was most recently adapted into the 2013 live action film 009-1: The End of the Beginning.
Changes through reprints[]
Originally when published in 1967, the manga's plot took place in 1985, with Mylene having joined the organization two years prior. It was also a point that she had been born in 1965.
However, as time passed, the 1980s setting was no longer relevant for a futuristic story. The manga's setting was thus updated to take place in 2065. The title was also changed over time, from 009ノ1 (creating a double pun with "ku-no-ichi"/kunoichi) to 009-1, more directly referencing Mylene's codename.
