Mirrorcle World is so iconic! When I went to my first exchange trip to Japan it was sponserd by JAL and the business ambassadors took us to a cafe where they played J-pop videos on huge TV screens. They asked who I wanted to see and I asked for Ayu. They played Mirrorcle World which had just come out (I didn't know about it because I was a casual fan at the time). We were all mesmerized and then the lingere scene came and the businessmen got embarassed and looked away from the screen and into their food LOL
