Synopsis
A van carrying a family that lives in Yono travels down a countryside road in Saitama prefecture toward Kumagaya. A local Saitama song called “It's Not Like We Chose Saitama” plays on the radio. It is followed by the DJ’s narration of a radio drama—the second chapter in the urban legend about Saitama.
Years ago, peace was achieved in the Kanto region (east Japan) when the citizens of Saitama, who were shunned by the citizens of Tokyo, put an end to the “passport” system after a grand farce of a battle. Rei Asami (GACKT) and Momomi Dannoura (Fumi Nikaido), who lead the Saitama Liberation Front, have launched a new project (THE SAITAMAFICATION OF JAPAN) for further peace. However, the project is stymied by the Saitama citizens’ poor connections with people in other prefectures.
To unite the citizens of Saitama, Rei comes up with a reckless plan to create a sea in inland Koshigaya. He and other members of the Saitama Liberation Front leave Momomi behind and set sail toward Shirahama, Wakayama prefecture, to bring back its beautiful white sand to Koshigaya. However, they get shipwrecked in a storm, and Rei alone drifts to a beach in Wakayama. There, he has a fateful encounter with Kai Kikyo (Anne) of the Shiga Liberation Front.
At the time, the Kansai region (west Japan) is under the control of Osaka governor Akira Kashoji (Ainosuke Kataoka), his wife and the mayor of Kobe (Norika Fujiwara), and the mayor of Kyoto (Mayo Kawasaki), who oppress the citizens of Shiga, Wakayama, and Nara prefectures. Shirahama has become a vacation resort for the Osaka citizens, off limits to anyone without a passport. Furthermore, a princess, the leader of the Wakayama Liberation Front, is being held prisoner there.
Kikyo tries to rescue the princess, and Rei tries to rescue his friends imprisoned by Kashoji. But Rei himself gets captured by Kashoji. Then Rei, Kikyo, Momomi, and their allies learn of Kashoji’s terrifying plot. Will they be able to stop his tyrannical rampage?! The situation develops into an unprecedented and unimaginable war between the east and west that involves the entire nation! The key is Lake Biwa? What does fate have in store for Saitama and Japan?!
