note: the first question is hard for me to understand, but is something like:
"-Right now, even though Kyari PamyuPamyu's story has turned up, regarding Idols' music, people who have come a long way have increased. Are you aware of that sort of existence?"
A: "Recently, MM has got a new member, and their dance work, with its formation actively changing, is immensily interesting! I'm thrilled while watching it, it's the best! I was thinking that I also want to do this!"
-Nocchi, please let us know from the start.
No: "Recently, right... Ah, I've watched MM's Help Me Youtube video over and over again (laugh). Since a junior from Hiroshima has become a member, I was worried, but with their 11 members, I believe their dance is amazing."
note: their Hiroshima junior Nocchi's talking about is Riho, who went to the same performing school as the Perfume members. Hence, she's their kouhai (junior)
another note: "ki ni naru" could be interested or worried, depending in the situation. I think Nocchi meant she was worried at first since it was her kouhai who entered the group (and hence, some sort of responsability), but she could've meant she was interested/excited, I'd thank some help in this one
