Eiro watched the movement of the arrow that was being shot, since it was rather unique. It didn't directly move in a straight line, it was as if it was seeking out the weakest spot of the target itself. Sure, it only changed its course to a minuscule degree, but it was certainly enough.
At the same time, the arrow was twisting around its axis, increasing the penetrative power an incredible degree. This was done through a mixture of subtle movements of her fingers, as well as direct control over the arrow as if through magic.
At this point, it was clear to Eiro who had summoned this girl. It was the god of the hunt, the greatest archer amongst all deities. He doubted that every single deity could summon them, so he tried to restrict his analysis on the greater deities for now, until he was shown otherwise. Who exactly summoned them didn't change all that much anyway, after all.
