Shadow, I need to say that Kirito had no idea that Asuna was an Undine back then. The screenshot shown in the anime did not show any kind of evidence that Asuna was an Undine. He did see an image of the world map before he joined Alfheim Online, so if he knew that Undine and Spriggan territories were next to each other, he could've took a gamble on that they had friendly relations
