I would meet anyone but here are a few ^_^
G_Yoshi cause we have a lot of the same interests, we would have a lot of fun hanging out.
Valder cause he's my homey.
Vash cause he's about the most level-headed person for his age I've ever met, and he probably has a nice anime collection (fun to watchx0r)
Kamuii and Birdbird, the two RL friends. I don't know what it would be like to spend time with them but I bet it would be quite an experience O_o
Lycia. She's a complex person and could probably hold a great conversation in person. Plus she is cool
I'm sure there are more, these just from the top of my head!
