Eiro activated the 'Blink' spell on himself and his body immediately started being pulled apart. His arcane magic enveloped his physical body and his cells, carefully cradling each minuscule fragment of his being. The demon could feel that arcane magic then pull those fragments away, like they were blown away in the wind.
Of course, that wasn't the case. The magic moved with specific, particular intention. His fully deconstructed body moved through the space in front of him. Luckily, his consciousness seemed to stay fully intact within this body as he moved along through this spell, so he could potentially use this spell on other people without worrying he would accidentally kill them in the process.
