No, Rasantark is spectating along with Kenntrips and Clarissa, they are the students in the front line by the side of Rauffen since part one of the Ditter Match. I do think the black haired captain have a name but I don't remember where I saw it.
I keep recognized characters that aren't yet named in the manga in the background, I wonder how many are there that are actual characters and how many are just extras.
Thanks for the chapters. And please do post chapter 31 as soon as you can, I've been following the raws too so I've been sitting on that for a little while and rather not wait too much to understand it. I think all the parts of chapter 31 are out already, guess it will be a while until 32 is all...
Very good ending. That was a good fake out there even if it was kinda obvious, but I like it how it wasn't just a gag but a set up that they picked up at the end. I actually like that the future marriage proposal was only implied, I am of the opinion marriage or pregnancy endings are overdone...
