Yeah, if it's not explained by then, I'd really appreciate more info on Bullet's Heat Up stuff (desperately hoping for Battle Fanatasia-styled Heat Up still :P).
And of course, anything about new Noel is always good too
Well in BB you're either NOL, a vigilante, S7, or some ancient superpower whose true power has yet to be seen, so she's got a pretty good shot at being NOL.
Except... she does... they look like Bolverk, they shapeshift like Bolverk, they work with her Drive like Bolverk, and they do Bolverk normals... it's Bolverk...
Further, something causes the burst icon to black out (as seen near the end when Amane does a DD, but it never occurs earlier in the trailer when DDs are done)
Let's not make conclusions on character changes based off of 6 seconds of individual gameplay. Let's wait for the upcoming loketests before even theory fightin'.
