There are no spoilers for season 3, just a normal skit that is pretty meta.
I think the art quality is slightly below what we are used to from the show normally, but that is more than made up by certain scenes which look incredibly and kaguyas normal over the top style.
Really there is nothing else to say, it is fucking kaguya-sama, is unnaturally funny like it always has been, watch it if you have watched the first two seasons.
