What I meant earlier by that the series isn't over is that Kiril calls Talos a liar becuase he realizes that there aren't just 12 songs (this must be where Wordplay, Screw, Gear, and Pride, and Recollective Musicbox comes in.)

Also they use the word "VOCALOID" in-universe now, not sure what context though. I wonder if the whole "reborn as vocaloid" theory is becoming valid.
