In 1996 came the commercial and critical success of Swallowtail Butterfly, a multifaceted story of the fictional Yen Town, a city of immigrants in search of hope and a better life with three separate and distinct main characters. Ageha (Ayumi Ito), an orphaned teenage girl, Glico (Chara), a prostitute turned pop star, and Feihong (Hiroshi Mikami), an immigrant who manages Glico's career and owns the Yen Town club. He also wrote the lyrics of a theme song for the film Swallowtail Butterfly (Ai no Uta) with Chara and Takeshi Kobayashi.
