Rico hadn't even noticed the dark figure appear behind him as it darted past him and Iris, heading right for the dark mage. Iris though was able to sense and turned to look at the newcomer, the remaining mana she had filling her eye.
After many years of using it, it was almost a reflex at this point for her to use it every time she encountered a new enemy. With it allowing her to see what kind of mana they possessed and how much, it was a useful tool for determining an enemy's strength.
As her eye landed on the dark figure, her body froze.
Her skin broke out into a cold sweat and her bones shivered uncontrollably as she gazed at the dark figure. They were wearing all-black clothing, the chest piece, and leggings composed of leather armor that was as dark as the rest of the armor.
