'In a world where we humans are inferior, the No Hearts stand tall. 

The No Hearts do not have a beating heart yet they live, exceed and dominate the city of Elixir which was once ours.'

899 years following the disaster of the Gold Stone 2100 Experiment, Ji Miho and her brothers travel to the prohibited city of Elixir to find out more about the No Hearts, a species of evolved 'super-humans’ who were formed as a result of experiment. For 8 centuries, these species have overtaken the human race, took their homes, their jobs, their life and suppressed them for many centuries yet no human has physically seen them.

With the intention to fight for their freedom, Miho and her brothers step foot into the world of the No Hearts and soon come to realise that this is nothing like they had imagined-

It is a world full of light, mystery and magic. Nothing like back at home.

Yet there was sadness within them. Within the No Hearts. Something that cannot be explained with just words.

They are suffering and no one can help them.
