บท 158: Control

"Concentrate, Leon." Eiro said in a strict tone, and the young boy sat in front of him with a quiet groan, "But Dad, I-"

"You're trying, I know that. That's why I don't want you to slip off and suddenly waste that effort. So come on, properly do it as I'm telling you." The Demon said, "Close your eyes and concentrate, alright?"

"Okay..." Leon replied quietly. Currently, Eiro was trying to help Leon get his skills under control by teaching him different mana-manipulation techniques that he could use while meditating.

As far as Eiro could tell, Leon's skills worked somewhat like an aura. Something that constantly surrounds him. And if that was the case, if it was that sort of energy, then it should be possible for Leon to control it as well.
