ZAIA Enterprise has successfully beaten Hiden Intelligence at the first match of the "5 Step Workplace Competition!" The next step in the competition involves selling houses, according to ZAIA's president, which consists of which company can sell more houses and make the most money, pitting Humagears against humans wearing ZAIASpec devices! ZAIA Enterprise will work alongside the industry's top real-estate salespeople, while Hiden Intelligence will make use of the real-estate type Humagear, Smile Sumida, whose motto is "Selling and living with a smile!" But just where exactly is this game headed? And who is the mysterious hooded figure spreading the Raidrisers around the city?
ZAIAエンタープライズが飛電インテリジェンスに仕掛けた“お仕事５番勝負”の初戦は、見事にZAIAが勝利を収めた。ZAIA社長の次の一手は、ズバリ「家売る勝負」。ザイアスペックを使った人間とヒューマギア、どちらがより家を売り、より利益を上げられるかという勝負だ。ZAIAが仕向けるのは業界トップの不動産の営業マン。そして飛電からは“スマイルで住まい売る”がモットーの不動産ヒューマギア・住田スマイルが立ち向かう。
果たして勝負の行方は？
そして、レイドライザーをばらまく、謎の黒い影の正体とは―――？
