A mysterious Box called "Pandora Box" discovered on Mars. The moment they opened the Box, a Big Wall appears before them. The Big Wall called "Sky Wall" is the beginning of the story. Japan's Archipelago split into three. Each of these had got their new capital called "Toto" (Eastern City), "Saito" (Western City) & "Hokuto" (Northern City).
Among these an Unidentified Lifeform called "Smash" appeared in Toto. They will put the humanity in dilemma without humanity's knowledge. Infront of them appears a young man who has a Belt around his waist and strange & mysterious bottles in his hand.
The young man who is a Genius Phycist transforms into Kamen Rider Build and fights the Smash.
Protagonist → Kamen Rider Build
Kamen Rider Build's Host is a Genius Physicist. Even in fight, he considers it as the Experiment. Using Different Full Bottle he changes his appearance. Among the Full Bottles there are only two Bottles which form the Best Match. When the Best Match is built, the Buildriver shouts "Moonsault of Silver. Rabbit Tank" (this is only for Rabbit Tank's Best Match).
Before transforming he says "Sa, Jiken wo Hajimeyouka" (さあ、実験を始めようか / So, Let's Start the Experiment) and during the finisher he says "Shori no Hosoku wa Kimarida!" (勝利の法則は決まりだ！ / Law of Victory is decided!)
Kamen Rider Build will also appear as a Guest Character in Kamen Rider Ex-Aid: True Ending premiering on August 5. He will fight Kamen Rider Para-DX in the movie. It's not known who will be the actor to play Kamen Rider Build but Toei said that there will be Press Conference on August 2 which will reveal all Cast and probably also the Artist who will sing the Opening Theme.
Kamen Rider Build will start airing from September 3 with schedule 8 AM to 8:30 AM. From October the broadcast timing will change to 9 AM to 9:30 AM
In the end, don't ask me which part of Japan would Futo belong to.
