Eiro turned his head to the side, and in the distance, he spotted something rapidly approaching him, "Huh. So I am in the right place." The Demon muttered to himself, accompanied by a deep sigh of relief that he didn't waste his time on this trip. After all, there was a wyvern, that looked quite a bit like the one that the Demon just met yesterday, coming at him.
From what Eiro could see, it was starved nearly as much as that wyvern from yesterday, and after spotting something edible, in this case Eiro, it came at him. The Demon just stayed in place and activated his Three of Swords. He really just needed a single blade, though, and to increase the size of it in this case, Eiro fused it with highly compressed air that he gathered within a few seconds before the wyvern actually reached him.
