The series is directed by Shuhei Morita, creator of the award-winning animation short Kakurenbo, and is authored by celebrated writer Dai Satō, Katsuhiko Chiba and Yuuichi Nomura.

The series openly displays its sponsor's product placement in numerous scenes in which characters are shown consuming Nissin Cup Noodles.

A second song, "Kiss & Cry", Hikaru Utada's 19th Japanese single, was used for Nissin's fifth television commercial for Freedom, which began airing in Japan starting April 20, 2007.

The remaining population declared the foundation of Republic Eden, then set forth expanding those lunar colonies that loved peace and freedom.

When his vehicle catches fire on a public road he is sentenced to 10 hours of "volunteer" work outside the dome, where he discovers the remains of a small crashed capsule bearing photographs and articles seemingly sent from Earth.

Infatuated with a young woman in the photograph, Takeru attempts to research conditions on Earth and finds that the library's information on the home planet is heavily censored.

As with most other major film and animation releases in Japan, a wide array of promotional merchandise was marketed before and during the OVA's release, including Nissin Cup Noodles with lead character Takeru printed on the lid, small desktop figurines, a 4 flavours Nissin Cup Noodles bundled Freedom DVD gift set, a limited Nissin Cup Noodle container and badges designed by video rental outlet Tsutaya that came free with the purchase of Freedom 1, among tie-ins with other retailers.

Publicity for the series began April 11, 2006, with large banners and posters featuring concept sketches of the lead characters Takeru, Kazuma and their vehicles lining Tokyo's busiest train stations, such as Shibuya and Shinjuku — the latter being the busiest railway station in the world with 3 million transiting passengers every day.

These initial pencil-work posters were later replaced by fully coloured, CG created versions with finished background art, giving the effect of a work-in-progress animation piece being completed.

Shortly before the Freedom 1 DVD release, many popular media, manga and animation magazines ran articles for the OVA, featuring mecha design descriptions and interviews with staff members.
