@WM I do believe that C9 either dislikes Ben 10, or thinks that it's a poor choice to compare SAO with Ben 10. Don't know which one applies to him or if either does at all.

Also, I doubt that Kirito and Koichirou would have even met in such a case. And even if they did, I doubt that they'd have anything that would bring them together.
