Kami Kuzu☆Idol

Yuya, one half of the boy pop duo ZINGS, may be the laziest performer in the Japanese music industry. His partner is out there giving 110% every night, but Yuya's sloppy dancing and his frankly hostile attitude toward the audience has the fans hating him and his agent looking for any excuse to cut him loose. The career of a pop idol just isn't the path of easy leisure Yuya expected... After a particularly lifeless concert appearance, Yuya meets a girl backstage. All she wants from life is to perform. There's just one problem: She's been dead for a year.
