Seta (Yes, I found another Seta cosplayer at Kcon! I recognized him in an instant and hugged him)
Naru
Motoko
Nagi (Negi's dad) (there was no way I wouldn't not know who he was) (wow, triple negative sentence) (wow, thir- fourth phrase in parentheses)
Kon (looking at you, Emerald ^_^)
Luna
And that's all that comes to mind at the moment.
