It seems to me that that Nuri has some sort of breath attack, since most of the images showing him have him "Huuuuu" breathing out before something dies or explodes. Though his breath attack must contain some sort of targeted attack because it hasn't hit team Tokyo yet. Additionally his attack didn't hit Nerdo, Kato and Anzu.
I think Reika, Old man and Sakata/Cherry will die. Most of the characters haven't really gotten much development and don't really seem to have much use anymore.
