I simply must talk about the last bit in which Yukarin goes around the stage and gives out stuffed animal thingies to people. As unfair and shocking(?) as it was, it was simply too entertaining for me. Heck, if I were there, and somehow managed to get one, I'd look around to see if there is a cute girl near me and just give it to her. I'm sure Yukarin would want me to do that, too. Ahem!
Oh, and I think I figured out why she wears those earphones. Not only are they for the music feedback, but I believe they're more for blocking other sound. Fans' cheers are delayed, and so can confuse the performer. We all know how loud they can get. Some people are apparently better at dealing with this quirk.
In the Cutie Cutie concert in 2005, she was more willing to touch hands with fans, but not this time around. Management decision?
Love the non-costume costume. I honestly like the look of her wearing a simple T-shirt.
Bonus requirement. Wearing a Lolita outfit helps, but only if you meet the requirement 1.
