Kamen Rider Build Tap 1 Today
Episode 1 of Kamen Rider Build ends not with a celebration, but with a question. Sento stands over Kasumi’s remains, Ryuga punches a wall in grief, and the Night Rogue watches from the shadows. The title card appears: “They Are the Best Match.” Who? Sento and Ryuga? Or Sento and his own lost identity?

Ryuga Banjo is the emotional core of Episode 1. He is arrested for the murder of his lover, Kasumi Ogura, a crime he did not commit. When we meet him, he is a coiled spring of anger—wrongfully imprisoned, betrayed by a system he doesn’t understand.
Unlike previous Riders who fought monsters in secret or parallel dimensions, Build’s conflict is geopolitical. The episode opens with a newsreel explaining “Skywall’s Tragedy”—a colossal alien structure (the Pandora Box) has split Japan into three warring states: Touto (the protagonist’s neutral-ish territory), Seito (the aggressive south), and Hokuto (the northern militarists).
