Be sure to watch Memi's face: it is often in motion, communicating even when she is not speaking.
I've been a fan of Memi and Kyouko right from the time of their auditions three years ago,. Here are notes about various things they mention:
01:54 “Cute lately” – Kyouko emphasizes that Memi has been “cute lately.” Perhaps she’s thinking of how upset she was around a year ago when Memi invaded her Showroom, romped around and tickled her – after Kyouko had told everyone not to come, that she wanted all the time with her fans. Then, Memi was being “not-cute” (i.e., not behaving nicely).
05:10 Hinanonano – They talk about Kamimura Hinano’s hand gesture for her name, and Memi shows how complex it really is. It’s so cute when their voices bounce back and forth in shrill surprise: Kyouko at the complexity, Memi that Kyouko didn't know.
07:10 how to grow taller – Kyouko explains what she did to try to get to 150cm (she's now 153cm - 5'-1/4"). Memi finds it all hilarious. Perhaps partly because she would like to be taller than her 157cm (5'-2").
