In the aftermath of a brutal civil war, Japan is being reshaped under the uneasy stewardship of three new governors, each promising a fresh start while the scars of the conflict still fester. The nation’s fragile peace rides on a precarious balance of political ambition and lingering distrust, creating a landscape where hope and suspicion walk side by side. Beneath the polished veneer of reconstruction, a hidden alien presence—the Blood Tribe—lurks, its members disguised as the very leaders tasked with unifying the country.

At the heart of this volatile world stands Sento Kiryū, a bright‑minded scientist turned hero known as Kamen Rider Build. Armed with ingenuity and an unwavering belief in building a better future, he becomes the focal point of the Blood Tribe’s plans. The tribe sees his resolve and his bond with friends as the greatest obstacle to their hidden agenda, and they begin to stir the pot, subtly turning allies against him and sowing discord across the newly formed government.

The story unfolds with a tone that blends high‑octane action, sleek sci‑fi aesthetics, and a brooding sense of political intrigue. As Sento navigates a landscape of public mistrust and covert manipulations, he must grapple with the painful reality that those closest to him may be turned into unwilling pawns. The atmosphere crackles with the tension of a nation on the brink, where every gesture could mask a deeper threat and every partnership is tested by unseen forces.

Against this backdrop, the film promises a thrilling clash of ideals: the drive to rebuild and protect versus an extraterrestrial scheme bent on annihilation. Sento’s struggle to safeguard his world while confronting betrayal from within his own circle sets the stage for a dramatic, high‑stakes confrontation that will determine whether Japan’s tentative new era can survive the hidden danger lurking in its own leadership.
