A high school student, Yume Mukai (Haruka Kaki), came to Sara (Ayami Nakajo), the daughter of King Enma. Yume is a hard worker who lives with her father's painter, Tetsuya (Jun Hashimoto), and supports the household budget by working part-time. As mysterious events continue around Yume recently, Yume is suddenly attacked by someone and threatened to 'don't get in her tune'. And immediately after she was released, her back of the head was smashed and she died. Yume, who doesn't want to die without singing her life, challenges her criminal reasoning game to bring her back to life.
