I have seen alot of pictures from her fanspace magazine and her best non fiction blog where she's being silly with her friends/dancers/staff etc etc. Yes, she's a shy person but I think that's because she doesn't open to people as easy anymore.
Does it really matter anyway? lol
And yeah

it's a bummer that Namie isn't on a-nation this year, I was hoping she would make it a regular thing lol. Maybe it's because her tour just ended and she needs a break? oh well, let's hope she's on a-nation next year
