I really don't want Bravo to die first. For that reason alone. I honestly want Gridon and Kurokage to die first since they seem to be phasing out the dance teams so it would make sense for them to die first as they are phasing out the two's attachment to the belts.
Guridon was seen in the opening battle, so it's highly probable that he'll be around for a long time to come.
I would like to see Bravo be that kind of character, because it would add more danger to the whole game.
