In a series of YouTube videos dubbed ARIA STATION, IA and ONE introduced their home-world known as Planet ARIA. IA has little background information, however she and ONE were given some through the ARIA - IA Musical & Live Show – performances. The design philosophy 1st PLACE worked toward was to make the voice simple and straightforward but easy to adjust and customize, letting creators create their own version of IA. IA is the first vocal of the -ARIA ON THE PLANETES- project.
