Nakadoi Hiroki (19), Taniuchi Shinya (17), and Kagimoto Akira (16), met at a dance school in Osaka. They were once known as a group called "FLOW". From the year 2002, they started performing in the streets (which is weird and creepy if you didn't know them). Meanwhile, Keita won the Fukuoka star light audition. Later he joined the group Flow. Then they changed their group name to Lead.
