Just two leaders meeting with their yandere, lovely girlfriends. Really sweet of Kiwi to take care of her partner. Dynamic duo between those two. Of course Kiwi had to strip but that's the type of shit Baiser loves about her anyway and I'm sure that helped cheer her up even more.
I also think it's funny every chance the author takes to remind people of the rules that will not be broken for Utena: we do not date magical girls or have interest in them romantically; we do not like magical girls actually falling; we will not be teaming with magical girls in any real sense.
They did this before with the chapter when Kiwi and Baiser fought the "magical girl x villain" enemy (while also pushing her to respect Kiwi x Utena) and did that again to a lesser extent here. "Will we team up?" "No, definitely not that's silly." I think Utena would throw up at the idea. The author definitely knows her audience and sticks to her vision.
