The only thing I can think about while reading her name (baiser) is a French equivalent of the verb fuck. (Also means a kiss but that’s less fun and possibly what the author wanted to use since there are some other French words ?)
I really liked this chapter (not just for that one bit). I just found this to be really fun and hilerious. I like how we went back to Hiiragi Utena being a manifistation of lust around magical girls and just wanting to mess with them. I loved Araga Kiwi as well, I found her antics in the background funny.
She came in her hand, Utena loved it and Azul knows who she is, what will Azul do with this information? Hopefully they have some more private meetings in their untransformed forms.
