At that time, the earth’s surface is not suitable for living anymore, so people built new cities on top of old cities and they kept stacking higher and higher. Two girls left their family and started a journey on their German half-track motorcycle, with the goal of survival and trying to reach “the top”. But they travel up to higher levels, they only found war machines and other leftovers of human activities.

Even though their findings were depressing, they did not hold the girls back. They kept looking for resources and moving forward. They even gave up their most valuable things such as the dairy and books to keep themselves alive. The girls’ desire for survival in a world full of despair is admirable.

Lastly, this is a poem by Hermann Hesse that was cited in this manga.

Out Wandering

Don’t be sad, soon comes the night,
When we watch over the faint countryside,
As the cool moon secretly laughs
And we rest hand in hand.

Don’t be sad, soon comes the time,
When we rest. Our small crosses will stand
On the bright roadside together,
And it rains and snows,
And the winds come and go.

Auf Wanderung

Sei nicht traurig, bald ist es Nacht,
Da sehn wir über dem bleichen Land
Den kühlen Mond, wie er heimlich lacht,
Und ruhen Hand in Hand.

Sei night trauig, bald kommt die Zeit,
Da haben wir Ruh. Unsre Kreuzlein stehen
Am hellen Strassenrande zu zweit,
Und es regnet un schneit,
Und die Winde kommen und gehen.
