Realised this, they quickly rushed to a wrecked delivery truck and found an injured driver. As Chase witnessed this, Heart appeared and present Chase three silver-colored Viral Cores as a gift from him and Brain. At the Unit's base, Eiji wondered the reason for Drive's disappearance for the recent truck attack and how did he even appeared in all Roidmude cases, figuring the latter as someone close to the unit. Furious at Eiji, Genpachiro and Shinnosuke decided to take on the job to guard oncoming delivery trucks. In Tridoron, Kiriko and Shinnosuke grew suspicious of the case since Font-R trucks were more targeted than any others. They received a contact from Eiji of a recent Roidmude attack on a Font-R truck. Shinnosuke as Drive successfully saved Genpachiro and fought the Roidmudes. While his men were fighting, Crush managed to get a strange object hidden in the truck. With this, their objective was done and they were called for a retreat. Drive however managed to kill one of them, Roidmude 060 until Mashin Chaser arrived for a rematch. In order to get himself overpower Drive, Chaser equipped the Spider Viral Core but evenly matched again when their finishers collided.

Nonetheless, he picked another bottle of explosive from the stolen briefcase and empowered himself to attack Drive. Drive finally understand the gravity of the situation: the Roidmude trios originally target medical supplement trucks for food but after they discovered and consumed the explosives, they became addicted to it, explaining the reason behind burned marks of the Font-R trucks.
