He plays undine.

I found it volume 10 this para:

Asuna met him several times in the real world as well, and she partied with his avatar in the world of ALO, the Undine Chrysheight. However, she felt that under his relaxed and friendly attitude, there was something hidden, an impression that she could not ignore no matter what, even now. He called himself a civil servant but had no permanent place and was often treated coldly, so perhaps he was from a department that was more exclusive —Kazuto had doubts about this as well.
