God I am excited for this set. As much as the Z riser had a lot of playability, I like how this is back to basics not really using too much of mixing older Ultramen as "form changes". The beam sounds you hear as inserted into the spark lens is the finishers.
for this style of bandai belt attachments I'd definitely recomend going out and buying a relatively thin black belt that fits you, consider even bringing the gimmick item holder with you to the store to find a good fit. I have just a normal belt at home that I can fit a lot of recent Kamen Rider "loop the belt through the buckle" style belts onto (such as the Buggle Driver, the Shot Riser, and the Jaken Caliburdriver) it's pretty nice
