Eiro took a long, deep breath as he let his mana flow through his body. It was a quite relaxing feeling and helped him get into a meditative state pretty quickly. And as he did, Eiro made sure to enhance his senses as much as he could.
He manipulated them to the extreme, making it so that he was practically only able to see what was going on in a five-meter radius around him, with everything else being a black void in comparison. And the Demon took on the right stance.
A few moments later, something came out of that black void, but seemed to practically disappear the next instant. But this time, Eiro was able to actually able to keep that figure in his perception. It was the wooden puppet, which Eiro was currently training with.
