Mira just absolutely LOSING her shit is comedic gold XD. She's like, "What the FUCK!" & "HOLY SHIT."
Someone else mentioned it, but she's really cute with the way she acts tough, but is actually rather flustered quite easily. I mean, it makes sense considering it would be too much of a leap to see one of her close companions strip butt naked in front of her male subordinate, especially since she didn't know about her power and the "reward" condition. She actually thought they got engaged lol, this cinnamon roll is too pure for this world XD.
I gotta say, I really loved that one panel of Kyouka hitting that Goddess pose fully naked and Yuuki's subsequent compliment. Can't believe it took him this long to take the chance to give her a compliment on her beauty during these "rewards" and try to rizz her up, which seems to have worked pretty well, as Kyouka blushed in response and had a very pleased expression afterwards.
Whilst I like Ren, Tenka, Himari, and even Shushu, I really want Kyouka to be the main girl that she was meant to be for Yuuki. Hopefully we get to see more genuine, intimate developments like this during their rewards, exclusive only to Kyouka, as a way to distinguish her as the endgame pairing.
