One day in the future, on another planet, there will be a continent called Asia Pacific. In this land similar to the earth, there are not only the descendants of human colonists in the feudal era, but also aliens they call "devils".
This is a story about a long contradiction card, a bow and arrow armor, and a battle against a well-known monster in the history of science fiction.
The protagonist is still the "big heroine": Helia, a nineteen-year-old young girl who is always thinking about how to defeat the devil and make a comeback for mankind. Although she is a respected senior "messenger", she is still unable to fulfill her ambitions because she is a woman.
The other two protagonists are Brandon, a fifteen-year-old boy with a full force level, and Colin, a sixteen-year-old boy with full intelligence. The former finally single-handedly killed the Alien Queen, and the latter discovered the key to humanity's comeback.
Concept: The protagonist's mental journey is similar to the mental journey we face when we face various challenges, from fear to despair to struggle. As long as we don't give up, there will always be a day when the clouds clear and the sun rises.
