In the setting of the story, a world far away from the earth, called 'Bluedria.'
There is a nomad girl, Haorini, who was a tribe leader of the White Fox Nomad, living as a normal person without remembering anything about her past memory.
During that time, Haorini unwillingly joined the company of prisoners who are going to be prisoned in the Dream prison, 'Sirabel.'
In the world of 'Bluedria, ' Origin, with a group of people who want to return to the Earth, have stood against the emperor Kunarion, who leads the opposition. 'Sirabel, ' is an imagined world that is the actual dream of the emperor Kunarion. He prisoned Origin and many of Origin's followers into his own dream, and he himself fell asleep for 200 years of time in 'Sirabel, ' which is 8 years of time in the real world.
When she came to Sirabel, Haorini forgot everything due to the shock of her entrance, even the fact that she is now in the dream, not 'Bluedria, ' the real world. However, she begins to understand many facts while she meets past companions, including Heath and Lenios. They volunteered to help her even though they cannot help but betray their leader, Origin. Haorini met Origin too, but she doesn't remember her close relationship to him. At that time, Origin was looking for his lost power, the ability of controlling time-space. When Origin realizes that the ability went to Haorini, he declares a war on the Kingdom of Gahelnai where Haorini lives in order to find her and get his ability back. Although Origin had to kill Haorini, he hesitated because of their past relationship and couldn't do it. While she stands against Origin, she realizes the falsity of the dream world. She also understands the fact that Origin and his people knew the truth already, and they have tried to use the 'Time-Space Power' for prison breaking. So, she decides to work together with Origin to escape from the Dream prison.
The victory of Origin and Haorini finished the war, and everyone returned to the 'Bluedria' at the end.
