Unlike in the previous run, Zeke doesn't have any named [Conjures] yet. In fact, most of his previous [Conjures] got wiped out except for Samael. However, the restriction still remains on this creature as, he can only summon it once he reaches [Level 100].
Hence, all that Zeke has are the [Conjured] version of all the opponents he defeated thus far. Mostly being Glade's soldiers within the demon continent. But, Zeke knew that these would be enough for the test he has in mind for the Elites.
They went back to the same area but this time, Heron is there to provide more protection. Zeke believes that the test may go out of control because of the slight training received by the humans from his two subordinates. This theory is further strengthened by the fact that Quinn and Kaguya are now with them – the humans who caused the most trouble for the demon general they faced.
