What is the language of the lyrics in "Replica" from Ghost in the Shell? https://www.youtube.com/watch?v=YtqMOKuUNHs

I couldn't find an answer on google or wikipedia. Copy pasting the lyrics into google translate didn't detect the language either.
I was puzzled by this question as well and I asked Ilaria Graziano herself if the song's language was real or made up, and she told me it's made up.

Check out the screenshot for proof.
