The Opening Bell Rings (開幕のベルが鳴る Kaimaku no Beruganaru) is the twenty-ninth episode of Kamen Rider Build.

It also features the full debut of Vernage since her brief appearance in The Idol Awakens.
Synopsis
Due to the settlement of the representative battle, the war will now end! At least, that's what everyone thought would happen. The war did not end, rather, it has gotten much worse. Blood Stalk, who allied himself with Namba Heavy Industries, is finally starting to set his plans into motion. Stalk, who had stolen 10 of the Fullbottles that were under Touto's possession, inserts them into the Pandora Box. All of a sudden, the Sky Wall begins to move, and a phenomenon beyond belief is about to unfold before their very eyes...!
Plot
While Namba (disguised as Mido) conducts an opera, Seito invades Touto once again, and Stalk begins inserting Fullbottles into the Pandora Box Panel. Touto's three Riders arrive to find Touto's forces massacred, and the Guardians significantly stronger than before. Once one of the panels is filled, it joins with the Pandora Box, causing the Sky Wall to shift suddenly. Misora and Taizan scream in horror as they watch a massive circular structure appear in the center.
