Kaiju then analyzed the battle earlier. He was not used to seeing Snow and Little Gorilla struggling in a battle, except against Qwanisha. The main reason for the latter was that they held back, and the constraint of adjusting with each other, especially on a battle formation.
Obviously, with dozens of Crimson Knights, spreading their Mana Aura, Snow and Little Gorilla has experienced its oppressiveness. Thankfully, most of the vampire players were not efficient in controlling their body, much less the Mana Aura.
Perhaps, the biggest advantage they only had was they possessed the body of an Overlord rank monster. It would indeed be difficult for the higher races to defeat them–Kaiju and his pets already struggled when they battled against a non-player Crimson Knights prior to obtaining the treasures.
