Most episodes are self-contained stories except for episodes 10-12 which combine to tell one story. Episode 13 is an extra episode that was never aired on television and chronologically takes place between episodes 4 and 5. It was included with volume 5 of the Japanese DVD boxed set release. Anime News Network's Theron Martin said the anime series "carries much of the style and flavor of Ishinomori's other iconic works like "Kamen Rider" and "Kikaider"" and noted "the series emphasizes Mylene's sex appeal by offering healthy and regular doses of fan service, although it leaves the most graphic parts to the imagination." He commented the character designs have "the same angular, caricatured look that all anime series based on Ishinomori's works have, with younger female “good guy” agents invariably being gorgeous sexpots and the bad guys (whether male or female) usually looking quite ugly." Martin also praised the musical score, saying it's "the other star of the series", aside from Mylene. Writing for Mania Entertainment, Chris Beveridge said "009-1" has "a good sense of pacing and style to it, going over the top in some ways but also keeping itself rather grounded in others. This is a world that I would love to see revisited on a more regular basis and lament that we're already more than halfway past it with this release." Bryan Morton from Mania Enterntainmente described it as ""James Bond" with women, "Najica" with no panties (no not in that sense), a cold-war "Ghost in the Shell" - sort of." Morton said "the stories themselves are fairly typical secret-agents tales - recover the scientist, prevent killings and so on - just with a slightly futuristic feel to them," but noted "all the stories hold together well and make sense." As the original manga is "so old", for him "it’s amazing that the show still feels contemporary." The kind-heart from the protagonist that is far more you would expect from a spy, "makes it different enough from other secret agent stories to really grab the attention, while the individual stories are a good combination of action and emotion that keep you entertained" in Morton's opinion. Derek Elley of Film Business Asia gave the film a 6 out of 10.
