A mysterious bacteria is infecting people in Zawame City. In the crisis situation, Kouta, Mai, and Mitsuzane try to find out the cause behind this.
- Bullying a Dragon: After the Inves plague breaks out, all of Zawame City blames the Armored Riders and openly scorns and insults them. Kaito shows how antagonizing people with superpowers is stupid on so many levels.
- Comically Missing the Point: When Oren takes to the airwaves to call out the Beat Riders, he uses the fact that he has employed Jonouchi as his apprentice as an example of how he plans to "discipline" the children. Mai completely misses the implied threat of violence, and instead becomes ecstatic over the prospect of getting to work at a pastry shop.
