For one, that sugary J-Pop in the PV is not the opening or ending.
Here's the earlier PV. Note the different logo for the poster and the first PV.
I'm really hoping that this is some huge fucking ruse and that all the cute girls get killed off in episode 1 after faking out everyone because the mecha are sentient and have some potential for a story.
A reminder that Tomokazu Sugita (Ragna the Bloodedge, Joseph Joestar, the joke character from GBFT) voiced a Kamen Rider's belt/bat buddy. This season was pretty bad and overwrought with drama, but the suit, viaul effects, and choreography were pretty damn good.
