Иру

Утау's first guardian character is Iл (first name). Iру is a true mischievous character, constantly arguing with Эру and loving rock music. When Утау became the master of X-Dia, Iру harbored a grudge and left with Эру to join Аму, but later, after being cleansed from X-Dia, returned. Iру can alter or transform a character's personality without the consent of the one being transformed. A bit later, Iру falls in love with Кукай.
