If you think Nana and Misato are speaking differently than usual at the beginning, you’re right. They’re trying to talk in a “manly way” with male speech. Funny how awkward it comes out sounding as they’ve both voiced male roles before (especially for Misato).
In keeping with this “manliness”, Nana does the “Smile-
Gang Fight” title call only be to interrupted by Misato.
Misato: Stop. Stop~ Not only is the BGM wrong, you’ve got the name of the program wrong too.
