Tonyu Tasamuki is a 13 year old boy with a voice and a dream he is often mistaken for a girl because of his girly figure. Before he became an UTAU he was just a sad little robot in a little brown box in the back of a electronic store. He was disigned as a singing robot toy for small children but he did not like the idea and he would only make high pitched noises so nobody could buy him. While he tried to escape the lonly box after a long attemt he managed to be rescued by a 13 year old named Josh Morin who was intrested with what was in that box. He then helped him develop a voice and started to get treated as a human. Now he is touring the work sharing his voice to everyone singing every note with care.
