Eiro looked within himself, inspecting his Mana Circuits. The first thing that he really tried to do once he got a good enough grasp of the concept was to practice manipulating them as quickly as he could. However, when he did so too recklessly, it was like a part of his physical body was being dragged along with it, causing sharp pain as well as a good bit of damage to the Demon.
