Kamen Rider Zero-One: Review: That Is 1000% the Best House

May 10, 2026
That Is 1000% the Best House” (Episode 20) is a solid conclusion to the real-estate competition arc, blending the show’s corporate satire with genuine heart. The episode centers on the Humagear Sumida Smile, who successfully demonstrates that a home’s value comes from the memories and smiles of its inhabitants rather than just market profit. This thematic win for Aruto is a direct rebuttal to Gai Amatsu’s “1000%” profit-driven philosophy, though the episode highlights the harsh reality that under ZAIA’s rules, human sales numbers still technically took the victory.
While the main competition provides a satisfying emotional payoff, the episode’s darker subplots steal the show. Isamu Fuwa continues to be a standout, with a sequence involving a haunting warehouse encounter that feels like it was ripped straight from a horror movie. This shift in tone, combined with the mystery surrounding his connection to Horobi, adds much-needed tension to an arc that some fans found too “filler-heavy”. Overall, the episode manages to balance a lighthearted real-estate battle with significant breadcrumbs for the series’ larger philosophical and technological mysteries.
