Sorry for being so late...I actually managed to watch her performance at C3!
It was 6 songs long, with some short breaks in between. I didn't know the first 2 songs, but the third and fourth were from her April 17 single, Sayonara Tteiu and the b-side. She described Sayonara Tteiu as a 'ballad', but it seems to be more in the cool-electric-guitar line. I liked it, anyway. The other song was more upbeat, and I was surprised by the lack of her usual chorus of voices in the background. The fifth song was uninstall, and the last was Anna ni Issho Datta No Ni.
30 people decided by lottery also got signed boards...(Not me of course)
She mentioned that her favourite food was chocolate, and seemed quite surprised upon hearing that women/girls actually received chocolates on Valentine's Day in HK (rather than giving only, as they do in Japan).
Other than that, here are some rough translations of her tweets:
わ!観るよお。wowow族だし。wが多いねwww RT @fion0806: 明日夜11時よりwowwowさんにてKalafina Liveの放映がございまする!ヽ(*^^*)ノhttp://bit.ly/W3rV26

最近はもう「歌」を歌ってるのではなくて、ただその時に感じるものを投げているだけのような気がする。で。もっと自由になりたいなって思う。突然、詞を頭でつくって歌うぐらいの。そういうのが私にとってのLIVEじゃないかって思う。
Recently, it seems that rather than singing 'songs', I'm feeling that [what I'm singing is] just the flow of emotions at that moment. I think I want to be more free. To the extent of singing lyrics that I make up in my head on the spot. I think that kind of thing is the meaning of LIVE to me.
猫ばんは。明日は「アニうた北九州2013」に出演します!
