Blood ignores the setback while combining the Hazard Trigger with the Pandora Box to destroy the planet at its core. Sento accepts as he turns into Build Genius, remaining determined in the losing battle before using the Gold Rabbit Fullbottle's power to extract Ryūga from Blood alongside Blood's kinsmen. The next day, Sento brings the Pandora Box to the governors with Inō going back on his word while challenging Sento to take Ryūga back by force. But Sento counters that Project Build allowed them to protect their friends while adamant that Ryūga is essential to Evolto's defeat. Sento engages Takumi in a metaphysical debate, his previous self lamenting over failing to honor his father's request as the aliens perverted his research for their schemes. Evolto belittles Sento while explaining that Inō only needs to Pandora Box to destroy the world, with a despondent Sento walking off before he receives a call from Inō offering to trade Ryūga for the Pandora Box. Once in a safe place, Sento wakes up from a dream of Takumi Katsuragi's memories of the Skywall Disaster where his father Shinobu told him that Ryūga is their ace against the aliens. Ryūga then gives Sento's Hazard Trigger to Inō, using it with his Cobra Lost Fullbottle and Ryūga's Great Cross-Z Dragon to become Kamen Rider Blood while absorbing his kin and Ryūga as Evolto carries the unconscious Sento away.
As Build is defeated, Inō reveals the populace truly consider Kamen Riders as reminders of the civil war's horrors. But Evolt's deviation from their plan forced the governors' hand with their Build Annihilation Plan, a brainwashed Ryūga attacking Sento as Kamen Rider Cross-Z. Inō explains he and the other governors are actually members of the Blood Race like Evolt and served as his co-conspirators in manipulating various events as part of their goal of destroying Earth. Sento hacks into a government facility's database to confirm the new governors as Soichi's Kiwami Project teammates before being confronted by Inō. The fight ends when Inō arrives, with Gōbara infecting a distracted Ryūga. After subduing Misora and Sawa once reaching Nascita, Sento attempts to call Ryūga Banjō who was abducted by the new Seito governor Mitsuomi Gōbara, provoking him into a fight after transforming into the Zebra Lost Smash while revealing himself to be responsible for Kasumi Ogura's death. The mob chase down Sento as Kamen Rider Build after he saved a boy and his older sister to a stadium, an unaffected Kazumi Sawatari and Gentoku Himuro covering his escape before their capture by the new Hokuto governor Ryōka Saiga as the Scissors Lost Smash. But the new Touto governor Kengo Inō rallies anti-Kamen Rider sentiment with the populace hypnotized into seeing Sento Kiryū as an enemy of the state.
