I really hope they don't add any unnecessary changes.

What I want to see the most is Usagi being all powerfull and badass in the scene where she saves all the girls who were kidnapped. I love how powerfull she is in the manga, but that scene makes me do all that fangirling... You guys surely know it <3

Chibusa and Diana.

I'm concerned about how they're going to handle episode 15 for the anime adaptation.  Maybe it's just me, but it always felt like the manga of that chapter was a little longer than other chapters were and there was a lot of ground they covered with lots of new characters introduced and the new story set up all in one episode.  I worry they'll either have to cut characters like Asanuma or Kotono out of the story or they'll have to really rush through the episode to fit in all this material in 22 minutes.
