Sexy 8 (セクシー8) was one of three special "shuffle units" from Hello! Project in the summer of 2002. They sold the most singles out of the three groups. The shuffle theme was "happiness" and Sexy 8 had a romantic song relating to finding happiness in a relationship. They released only one single, "Shiawase desu ka?" (幸せですか？; "Are You Happy?") which included their version of a c/w song that was shared by all three shuffles. True to their name
