Since releasing their debut single I'm Real in 2021, K-pop girl group Eternity have racked up millions of views online.
They sing, dance and interact with their fans just like any other band.
In fact, there's mainly one big difference between them and any other pop group you might know - all 11 members are virtual characters.
Non-humans, hyper-real avatars made with artificial intelligence.
"The business we are making with Eternity is a new business. I think it's a new genre," says Park Jieun, the woman behind Eternity.
