IA is the first vocal in the "- ARIA ON THE PLANETES -" project.
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 taken from her voice provider's name, "Lia".
There are at least two ways to read her projects name of "- ARIA ON THE PLANETES -":
- The words "Aria" and "Planetes" are Latin and Greek for "open
space" and "planet" respectively, giving the translation of "Open Space on the Planet".
is also the Italian word for "air" and is used as a term in opera for expressive pieces, usually sung by a single singer. This also fits in with her more opera-esque vocal results compared to other released Japanese Vocaloids.
When she was first released, overseas fans often mistook "Aria" as the name of the Vocaloid.
Her design was illustrated by Aka Akasaka (D. Z.), while the design direction was by Maxilla Inc. It was decided that they would go for soft colours instead of Vivid ones. At the time, there was skepticism towards avoiding vivid colours as there was a fear of her not selling because of the softer tones. Lia herself wanted her to be cute and pretty and was satisfied the first time she was shown the artwork.
Despite the myth of IA's age being 15, she has had no age assigned to her. This myth seems to originate from a section underneath the paragraph on IA about her provider Lia, wherein one of the first things mentioned was that Lia debuted in America at 15 years old.
