"Eden of the East: Air Communication" is a compilation film that condenses the events of the 11-episode anime series "Eden of the East" into a single narrative. The story begins with Saki Morimi, a young Japanese woman visiting Washington, D.C., who encounters Akira Takizawa, a mysterious man who appears naked in front of the White House, holding a gun and a cell phone. Takizawa has no memory of his identity but possesses a phone loaded with 8.2 billion yen in digital currency and access to a concierge service called Juiz, which can fulfill nearly any request.

The narrative unfolds as Takizawa and Saki return to Japan, where they discover that Takizawa is one of twelve individuals known as "Seleção," participants in a game orchestrated by a shadowy figure called Mr. Outside. The game's objective is to save Japan from its societal and economic decline, with each Seleção given vast resources to implement their vision. However, failure to make a meaningful impact results in elimination, often through assassination by a figure known as the Supporter.

As Takizawa investigates his past, he learns fragments of his involvement in a mysterious event called "Careless Monday," where missiles struck Japan without causing casualties. His memories gradually return, revealing his connection to the game and his role in the incident. Meanwhile, Saki becomes increasingly involved in Takizawa's mission, aiding him as he navigates the complexities of the game and confronts other Seleção, each with their own agendas and methods for "saving" Japan.

The story explores themes of identity, societal responsibility, and the consequences of power, as Takizawa grapples with his amnesia and the moral implications of his actions. The film retains the core plot points and character dynamics of the series, focusing on Takizawa's journey to uncover his past, his relationships with Saki and other key figures, and his efforts to outmaneuver the game's deadly stakes. The narrative builds toward a climactic confrontation that ties together the threads of the mystery while leaving room for further exploration in the subsequent films, "The King of Eden" and "Paradise Lost."

Key characters include Akira Takizawa, the amnesiac protagonist driven by a desire to understand his role in the game; Saki Morimi, a compassionate and resourceful woman who becomes his ally; and Juiz, the enigmatic concierge who assists the Seleção. The story balances intrigue, action, and emotional depth, offering a compact yet comprehensive retelling of the original series' events.
