Once, there were two gods. Vivace and Morendo. They found a neat little thing they called music, and created beings to play it for them.
They were the first Noetta. They all lived in a place called the Symphonic Serene, which was a bit like heaven!
They played music for the gods every day... pleasing them.
That was, until Cleo came along.
Cleo wasn't as good as the other Noetta, making the gods feel displeased with her. Therefore, her kind - the novice Noetta - was banished to Earth to learn about music all by themselves from the humans.
The Noettas needed to hide from the humans, therefore taking a human-like appearance. Um, yeah. No one will spot you there, Cleo. Totally...
The population of Noetta slowly grew and grew on Earth, and so does the weird number of talented musicians.
Take this as a lessons for you gods to stop dumping your strange creatures onto Earth.
Nowadays, Noetta try their best to play the best music, to try and please the gods and return to the Symphonic Serene.
