I need help on the tags. I'm not sure if that's Kaga or Souryuu (or even Zuikaku) in the background, and it's just that their twintails are not shown because of the angle. That "Hibiki" might also be Shimakaze with shorter hair and none of her other distinguishing traits. (Although I'd expect Rensouhou-chan to show up with her...) I keep adding a few more on, but I'm sure I'm still missing a couple other tags, as well...
EDIT: I was looking right at her, tagged her side_ponytail and hair decs, but still failed to remember to tag Akebono herself... *facepalm*
The one on the floater is Kaga due to the clear side ponytail. And Hibiki has slight wavy hair so things are spot on. I am concerned about the Ushio though since the face is quite generic and I believe the one with the spear is Akebono due to her flower in her hair.
