How many characters can you name (via)? No fair looking up in your stack of screencaps, do it cold.

For me, Luccini, and, to an extent, Barkhorn and Sanya are dead giveaway. A moment of thinking uncovers Miyafuji and Sakamoto. Finally, I think I can spot Pierrine, based on character traits. The rest is a mystery, however. I'm not that much of a fan, apparently.
