Actress/singer Kou Shibasaki and rock band Group Tamashii have announced that they are forming a new unit called "Group Tamashii ni Kou Shibasaki ga." Their debut single, "Omae Low Tension Girl," is the theme song for the upcoming movie, "Maiko Haaaan!!!"

Shibasaki and two of Group Tamashii's members, actor Sadao Abe and screenwriter Kankuro Kudo, are involved in the movie. Abe stars as Kimihiko Onizuka, a salaryman with a penchant for maikos (apprentice geishas), while Shibasaki plays the role of Onizuka's ex-girlfriend and co-worker. Kudo is in charge of the screenplay.

The movie will be released on June 16. The single will go on sale on June 13, but it will start playing in movie trailers this month.
