Japanese Civil War

The Japanese Civil War was a nationwide conflict that broke out in Japan of the World of Build ten years following the Sky Wall Disaster which split the once united island into three separate nations. Though ostensibly a three-way war between the nations of Touto, Hokuto, and Seito, it was more accurately a conflict between the pacifist Touto, supported by Kamen Rider Build and his allies, against the warmongering Namba Heavy Industries Ltd. and their benefactor Evolto, whom manipulated the nations of Hokuto and Seito into invading Touto while conspiring with their Deputy Prime Minister Gentoku Himuro to undermine his father, all in order to seize the Pandora Box and gather the 60 Fullbottles needed to open it.
==History==
===Prelude===
War is not an unknown concept to the alien race known as the Blood Tribe, and has been one of their main strategies in attacking planets they conquer and destroy. However after their king Killbus had destroyed their planet, the Blood Tribe escaped with the Pandora Box to the planet Mars, where its queen Vernage would seal them into the Pandora Box. For years, the box as well as Vernage's bangle had remained on the planet. 
===Preparations===
In 2007, the Institute of Space Engineering Technology sent an unmanned rover out to Mars, however a piece of Evolto had escaped the box and latched onto it, which it later possessed Yuri Banjo and fused with her unborn son Ryuga Banjo in order to gain an initial reconnaissance of the planet. Several years later, INSET launched the Kiwami Project by sending a four-member expedition team on the Prominence to the planet. One of their members, Soichi Isurugi became known as the one who discovered the Pandora Box as well as Vernage's bangle and brought it down to Earth. However unbeknownst to any of the four members, they were possessed by the souls of the tribe and manipulated their way into national politics. 
The Blood Tribe would then orchestrate events that allow Shinobu Katsuragi to discover their identities and move forward with Project Build, a series of weapons designed for sinister warfare, yet Shinobu had also secretly designed the Kamen Rider system to combat against them. After Shinobu's exile, his son Takumi Katsuragi took over the project and subsequently discovered the Blood Tribes' identities. Wanting to back out because he was falsely led to believe that he was truly acting for the sake of justice and not for bloody war, Kengo Ino ordered Evolto to erase his memories and turn him into Sento Kiryu, who later would unknowingly contribute to the advancements of the war by being Kamen Rider Build.
===The War===
The first phase of the war began when Hokuto, supported by Blood Stalk, launched an invasion of Touto following the supposed elimination of the terrorist organization Faust, which was secretly managed by Gentoku Himuro. Gentoku became Prime Minister in light of his father's ill health, only to be banished from the nation once his father was healed by Misora Isurugi, with the younger Himuro's true nature being exposed. Ultimately, the conflict between Touto and Hokuto was decided by a Proxy Battle in which Touto emerged victoriously.
The war continued, however, as Seito, having initially remained neutral while being secretly backed by Juzaburo Namba himself, quickly seized control of Hokuto, who had been sold out by Stalk, before launching their own invasion of Touto. Ultimately, Seito was represented by Gentoku Himuro as Kamen Rider Rogue in the deciding match of the 3-on-3 Proxy Battle against Touto, who was supported by Hokuto's Kamen Rider Grease. When Touto prevailed against Seito, Prime Minister Masakuni Mido, though devastated, intended to honor his promise to relinquish his claim on Hokuto, the Fullbottles, and the Pandora Box, only to be murdered by Blood Stalk, who applied his appearance to Namba, allowing the CEO to secretly take control of Seito personally and pour the full might of his corporation into an invasion of Touto.
