Superior

After staring long and hard at the black hooded guy (Kara), Rabbit had turned around. In the corridors of the second floor, he walked and then arrived in front of the body of his dead subordinate. Clearly, Noah was dead. 

He also saw that his black heart had been utterly crushed. 

It was obvious that the enemy knew how to kill hell demons. 

"What faction could he possibly belong?" 

If Rabbit had not seen the enemy's shadow demon form, he would have thought he was a natural mage. Someone who worked for a power political leader. Or an organizations which knew of the existence of hell demons and how to kill them. 

Bu that seemed to not be the case. 

Rabbit had arrived to a conclusion that the enemy belonged to another faction of demons. That could be the only explanation for it.
