I can't make a positive ID on a few of these characters. I'm guessing that's Satsuki and Fumizuki on the left purely by the sheep doll having made an appearance with the two before.

The girl on the far right, I can only make a blind guess based upon her being a non-Fubuki-series destroyer.

Also, is there any tag for whatever is on the stand Ushio's in front of?

(Oh, and Twitter comments asked about whether it was safe or not for Mutsu to be so close to a heat source...)

This needs the translation to be finished.
