After Hase transforms into an Inves, Gaim tries to take him out before he can do much damage but finds it difficult to harm someone who he believes is still human inside. Meanwhile, Baron does his best to combat Zangetsu Shin but is overcome by Kurokage Troopers and captured. And Mitsuzane, who realizes his brother is their foe the white Armored Rider, infiltrates the Yggdrasill Corporation headquarters on his own to see what is truly going on.
Hase flees after transforming into the Hekija Inves and Gaim pursues him while Baron confronts Zangetsu Shin by himself. Refraining from killing a human, Kouta corners Hase who barely returns to human form, although still under the fruit's effects and attacks Kouta before escaping. Meanwhile, Zangetsu Shin defeats Baron and Kaito is captured by the Yggdrasill Corporation's Kurokage Troopers. Kouta returns to Team Gaim's base and when Mai and the others ask him about what is happening, he claims that he cannot explain the situation at the moment and leaves to keep searching for Hase. The next day, Takatora returns home briefly and Mitch hides inside his car to infiltrate the Yggdrasill Corporation's facility. Hase appears at Drupers, and after trying to eat the fruits there, he attacks Rica, but Rat gets hurt trying to protect her, and after Hase flees, he is taken to the hospital. Elsewhere, Mitsuzane witnesses a meeting between Sid and Takatora who discuss the mass production of the Genesis Drivers before they are informed of Hase's location and leave in a hurry. When Mitsuzane enters the room and searches the research files, he watches a video of Ryoma explaining how any organisms that eat a Helheim Forest fruit has its DNA rewritten and is transformed into an Inves. In another video, Mitsuzane discovers, much to his horror, that Yuya Sumii ate fruit and transformed into the Byakko Inves that Gaim destroyed months ago. Meanwhile, Gaim tries to calm down Hase with no success until Zangetsu Shin appears, accompanied by three other New Generation Riders using Genesis Drivers. One of the other Riders, New Generation Rider Sigurd, drives Gaim away from the Hekija Inves before destroying the Inves and reveals himself as Sid. Kouta confronts Sid for killing a human being just before he is restrained and captured by Kurokage Troopers.
