In Kamen Rider Zero-One Ep. 26: We Are The Flaming Fire Brigade, the fourth round of the “5-Round Workplace Showdown” between Hiden Intelligence and ZAIA Enterprise has arrived! This time, it is a showdown among firefighters! By creating drills simulating real-life fire scenarios, both sides will determine whether a Firefighter-Type Humagear or a human firefighter with a ZAIA Spec will be able to rescue the most civilians! A building has been set up to recreate a rubble rescue on the basement floor, the first floor from a fire rescue, and the second floor from a smoke rescue! However, suddenly during the midst of their competition, a mysterious Raider appears and causes an explosion!
