In Kamen Rider Zero-One Ep. 20: That Is 1,000% The Best House, the second round of Hiden vs ZAIA’s Workplace Competition is a real-estate competition! ZAIA’s top real-estate salesmen, equipped with the ZAIA Spec, utilized some underhanded manoeuvres to undercut Hiden’s Real-Estate Humagear, Sumida Smile! The showdown between humans and Humagears now rests in the hands of a seemingly human victory, but just then, a couple of millionaires on a budget seek to purchase a house of their own! It is not an exaggeration to say that selling a house to a millionaire will essentially win you the competition, so the final battle between a restored Humagear and the ZAIA Spec human will now begin!
