Its leader was Shin'ichirō Wada (和田 真一郎 Wada Shin'ichirō?, born July 30, 1974, in Kawasaki, Kanagawa Prefecture). They were convicted of raping three women, but the real number of victims is unknown.

Super Free was established as a university social club in 1982. Wada was a student at Waseda University before being arrested. He entered Waseda University in 1994 and became the organizer of "Super Free" in 1995. It had 14 members as of 2003. Super Free was a highly successful inter-university rave event club, to the point that it was incorporated, having 5 branches nationwide, 30-odd employees and an office in Roppongi. According to the indictment, the club organized parties and social gatherings at a public night-club in Roppongi. The members of Super Free would scout for potential victims among the public, and befriend them offering drinks. Once their victims were intoxicated and incapable of resisting, they would lure them to an abandoned room. Wada was arrested on June 9, 2003. His circle's 13 other current members were also arrested for gang rape. Super Free was dissolved on June 22, 2003.
