If there ever is a Queen mum to show up I wouldn't mind no odangos but I would miss them. I'd like to see her and with some sort of elaborate hairstyle, befitting a queen. There has to be some sort of history about the moon kingdom and the the soldiers of the other planets. Without other people from the moon kingdom I can't imagine how the writers would be able to keep things interesting. I demand more characters! Sailor Luna doesn't count!
Seriously, what about Artemis!? I'm having a lot of trouble with Sailor Luna being anything but temporary. If she is, than I think she's a great idea! Otherwise I make funny noises that indicate doubt. It would be awful cute to see Artemis as a person too. I imagine his feelings would be hurt otherwise. Anyway, Mamoru should have to be the only male hero in the story. If Motoki gets his turtle power on, then maybe we'll see some evening of the playing feild.
I think that Queen Serenity wont even show up. Its sad, I would have liked to see how the producers made her like. But since its a different serie, I have the feeling she wont come or if she will, in a long time :S
