I think it'd make sense for Gremmy to kill Kensei and Rose with his imagination and not physically since he relies solely on that and never doubts its effectiveness.

Toshiro and Rangiku were found by Giselle first, and since it's better to have living zombies than dead zombies she kept them alive.
