Utau is a 14-year-old junior high/high school student model turned into singing idol. Utau Hoshina is actually only her stage name, since her actual name is Utau Tsukiyomi (月詠歌唄 Tsukiyomi Utau), and is Ikuto's younger sister. She is in love with Ikuto and is constantly trying to win his affection, and thus becomes extremely agitated when she notices that Ikuto is interested in Amu Hinamori. However, she eventually becomes vrienden with Amu. Utau was both independent artist (with her hit song, Meikyuu Butterfly) and the vocalist of the indie band "Black Diamond", produced door her manager, Sanjo Yukari, as a method of using the CDs of their muziek to draw the eggs out of children and make them into X-Eggs. When the plan fell apart, Utau quit Easter Company with her manager and became a singer on her own, without Easter contracting her. Utau has very long blond hair in 2 ponytails and purple eyes. Utau is a little taller than Amu and the other female guardians, seeing as she is older than them. She is also seen wear a silver kruis around her neck, but she wears it as meer of a fashion symbol than a religious one. She is often seen in different and fashionable clothes. Utau is also seen in disguise almost all the time when she is in the streets of parks. Her basic disguise style is a brown hat which her long hair is tie up and put in, a pair of sunglasses that is dark in colour of a pair of reading glasses with her 2 ponytails tied to pigtails. In episode 39 of Shugo Chara Utau never took off her Sunglasses even at night to hide from Amu and her fans. Also in episode 74 she was never in disguise so people knew she was Utau and Amu told her "Should u be in disguise of a hat of pair of sunglasses" while Utau zei "Why should I be sneaking around here".
Utau, naturally sings often, but also enjoys many types of food and eats a lot. She is often seen hanging out with her good friend, Kukai, and eating ramen with him.
