HADES: Circle is described as a naive girl with a pure and wild voice and tender skin. After her transformation by Hades Tech, where they downloaded the world's obscenities into her system, she became something vile, seductive, and unforgivable. After she was captured by Hades Tech, they used cutting-edge technology to download the world's obscenities directly into her system. She was then made into a pop star with the purpose to ban human artists once and for all.
