Midnight Crystal (Part 87)

Plague Reaper was not just an experienced and intelligent monster, he also had a lot of knowledge about how the world worked, what was happening in the Dead Lands, who the Phantoms were, and what they were capable of.

That was why Plague Reaper was still alive, killing the most creatures, be it monsters or Phantoms, of any Purple Threat Level monster.

He knew how to keep Adam and the others from getting help from the Citadel. Sure, Nessa was here, but almost no one in the Citadel was aware of XH-01's existence, let alone the monsters living in Dead Lands.

Thus, when he saw Adam and Katrin heading towards the Essence Scarlet Pyromancer, his eyes opened wider than ever.

He realized that he had just been outplayed, the mere fact that he hadn't noticed that there was another Purple Threat monster from the Top-10 was already a true failure for him.
