Chaser Bat fired his arrow, but as it is about to hit Kiriko, he mentally navigated it to miss his target, leaved them unharmed in the end. Furious of his actions earlier, he yelled under his anger for somehow remember Kiriko. In the Drive Pit, Shinnosuke awakened after 15 hours of losing consciousness.

Midnight Shadow Shift Car was tailing Kusaka when suddenly Roidmude 033/Scooper fired him to prevent Drive's interference. As Shinnosuke returned to the Special Investigation Unit's base, he was shocked to discover Kenta taking photographs of the office. Jun revealed that he purposely let him doing it since they had low budgets recently. Kiriko reported Midnight Shadow had lost sight of him. At Touto Times office, Kenta revealed Kusaka's earliest work, the explosion of the Font-R factory. Ever since that, he became obsessed with fame. Kenta admitted that he was trying to search Kamen Rider so that he can save his friend, Kusaka, whom was under influence of Scooper.

He also believed the whole event was his fault since he had given up the Kaishima Building case a year ago and no matter how much photos they took, they would be accused for fraud. Kyu contacted them and revealed several infos. All of the collapse buildings belonged to politicians that affiliated with Kaishima City Construction. All were destroyed in the order they were built and the final target is an international sport stadium. While Shinnosuke drove them to the place, Chase stopped them. Shinnosuke ordered Kiriko to take his place while he fought Chase. As Mr. Belt arrived, Shinnosuke and Chase transformed to fight, using Drive Type Wild and Chaser Tune Chaser Spider.

Arriving at the stadium, Kenta apologized to Kusaka but he refused and had Scooper terminated them before he revealed Kusaka as his victim as well. Rinna appeared in the battle and gave Drive a new gun, Door-Ju. The fight continues but as Chaser sees Kiriko's illusion, he retreated. Arriving at the sport stadium, Drive first overwhelmed him with Tridoron Type Wild and finished him as Type Speed via Full Throttle Rider Shooting. Before Kusaka was brought to custody, he redeemed his actions and along with Kenta decided to uncover Kamen Riders' mystery for their next article project. Kiriko finally able to meet Hayase in person which Shinnosuke promised to Hayase but never fulfilled it. Hayase finally figured out that he didn't wanted Kiriko to find out Shinnosuke's secret.
