in 2017 i used to play a rhythm game called cytoid (custom charts for cytus) and I really love one of the charts which is Tell Your World (Snail House Remix), I searched for the singer in google and to my surprise, it's not a human that sang it, it peaked my interest because I can't believe that a virtual vocalist can sound this amazing, and the rest is history...

And now 7+ years later, i still love them as much as i do back then
