Eiro looked at the boy curiously, not sure what he was supposed to expect. Clearly, the other mages had also already realized what was going on. That this boy had cast magic without the use of a wand, and that he created a magic circle in an instant like that.
However, the magic circle itself seemed quite... basic. It was a simple air magic spell. An air bullet, nothing else. Or at least, that's what Eiro thought. In a moment, an incredible amount of air was gathered and compressed into a bullet. Compared to the mana used, and the complexity of the magic circle... That bullet was far too powerful. One more thing that convinced Eiro that this boy was summoned by the god of magic. Increased magic potency.
The bullet shot forward at an incredible speed, and ripped apart the monster that had been prepared for him. It looked like someone had shot explosive magic at it, the way that its parts splattered around like that.
