The year is 2050.
Young engineer Derrida Yvain became famous thanks to his contribution to the development of “Autonomous Machine DZ” at Rebuild, the manufacturing company founded by his father.
One day, Derrida and his colleague Nathan find a serious flaw in the “DZ”s and try to warn their boss but are ignored.
Although aware of the danger, they reluctantly decide to put off taking any measures and go to Nathan’s daughter Mage’s birthday party.
Next day, after spending a peaceful time, Derrida and Nathan are suddenly attacked by unknown forces.
At the end of the escape, Derrida falls into a cold sleep machine and 10 years later, he wakes up to a devasted world in the middle of a war.
Being attacked by a group of out of control “DZ”s, Derrida almost gives up but he recalls Nathan’s last words.
“Take care of Mage.”
Despite the harsh fate that has fallen upon him, Derrida sets off to seek Mage.
Beyond the time, we reunite –
This is the story of a journey of hope.
