The operation is turning out to be extremely costly. Clearly they need to do better when they go after the next member of the ink clan royalty. Though the Evolution Pass occupier might have been a bit more difficult than many others due to the number of rank eight ink disciples. Though at the same time, since the ink king needed to guard both his own capital (nest) and the Evolution Pass, the humans could use a strategy to divide his forces. The royalty facing the other passes don't have such worries.
