[Shin Henshin]

It's kinda surprising to see so many people say the dancing is pointless when technically it's where all of this kinda started.

Kouta was the first of the Beat Riders to use the Sengoku Driver and what use did he find for it? Fighting in the Inves Games for Team Gaim. It only ended up escalating from there with every other team looking for stronger lockseeds or hoping to get a hold of their own drivers to the point where it became more of an actual war. Add the fact that they were the only ones who had access to the Inves Games, thanks to Yggdrasil, and it only makes sense that the public would turn on them once things got more out of hand.

Saying Mai wants to "save everyone with dance" seems way too broad to say. It's more that she's sick of seeing people aim all their anger towards the Beat Riders, knows that it's effecting all the other teams and thinks the best thing to do to try and start changing the minds of the people is to go back to square one and start doing their group dances to entertain like it was originally and not to battle over popularity.
