In a remote corner of the world, surrounded by a purple fog that only allows life within its limits, lives Aka, a girl born with a fragile body and condemned to a short life. In the small, quiet town in the valley, his days are filled with quiet explorations, observing the world from the shadows while dreaming of doing the same as everyone else.
But one day, the silence is broken by an explosion at the entrance to the valley, one that brings with it not only destruction but a dark change that will affect his entire life. With her people in danger and the protective figures she loved now absent, Aka is forced to fight for her survival and uncover the ancient secrets that shroud the valley. Facing hidden threats and challenges that will test her will, Aka will embark on a journey towards the truth and, perhaps, towards the strength she never thought she possessed.
