Ema has worked really hard to achieve her goal of becoming a singer. After debuting as a member of the eight-member idol unit "Lu-ce", she achieved success and renown as a tremendously popular idol. Yet in a group known best for perfectly synchronized dance sequences, it wasn't possible to shine through with her singing. Ema had lost sight of her original goal and was losing interest in show business, but after coming into contact with the popular idol group "Un:Finish", her life began to take a new turn.
