The name "Gumi" is the voice provider Megumi Nakajima's nickname from her childhood. The software name, "Megpoid", was taken from the provider's name "Megumi." The second half, the "poid", is short for "like Vocaloid," the full implied name of this product is "Megumi-like Vocaloid."
Her design is often said to be influenced by Ranka Lee's character (one of the first roles done by Megumi Nakajima as seiyuu). Ranka Lee's main outfit contains the colors green, yellow, and orange. This has never been officially confirmed, but is still a popular assumption with both Japanese and overseas VOCALOID fans.
There is no official age given to GUMI, but it is set around the teenage years.
