The end of the world caused by human arrogance,
Created monsters and mutants who were no different from monsters but barely retained human consciousness and form.
There is an irresolvable gap between ordinary people and mutants.
The only thing left behind is the children.
This is a story about their efforts to survive, and also a story about their helplessness.
The beginning of this story still has to start with the young man.
Purpose: May we not lose courage in despair
