Bleach Volume 64

After being confronted by Yachiru with her Shikai Sanpo Kenjū, Guenael is revealed to be a creation of the real Sternritter "V" Gremmy Thoumeaux, who used his imagination to create a distraction so he can kill off Kensei and Rose. Gremmy proceeds to overwhelm Yahiru before facing Kenpachi in a battle. At one point of the battle, Gremmy summons a meteorite over the Soul Society, but Zaraki uses his Shikai "Nozarashi" to destroy it. Seeing that he can't defeat him, Gremmy decides to imagine himself powerful as Zaraki but ends up being killed by his own imagination. But Kenpachi's victory is short-lived when he and his Squad 11 subordinates are ambushed by Giselle Gewelle, revealed to be Sternritter "Z", and her three associates Sternritters "T" Candice Catnipp, "G" Liltotto Lamperd, and "P" Meninas McAllon.
