Kamen Rider Build: Be The One (劇場版 仮面ライダービルド: ビー・ザ・ワン Gekijō-ban Kamen Raidā Birudo: Bī Za Wan)[2] is an upcoming film of Kamen Rider Build, double billed with the Kaitou Sentai Lupinranger VS Keisatsu Sentai PatrangerIcon-crosswiki movie, Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger en FilmIcon-crosswiki.


Set after the events of the series, Seito, Hokuto and Touto now support each other in their mission to reunify Japan, with new governors leading each region instead of prime ministers. However, they are part of an evil organization called "Blood Tribe", which intends to take over the entire world. Being certain that Sento Kiryu/Kamen Rider Build is a major threat to their plans, they proceed with their "Build Annihilation Plan" (ビルド殲滅計画 Birudo Senmetsu Keikaku) to manipulate Sento's friends and other civilians against him. The trailer also teased the "destruction of a bond between two partners" and that "those two can bring about a miracle."
