The world we knew is gone. The massive cities, once filled with people, lie silent, empty and decaying. There are no more forests filled with animals; no more birds in the sky. But life hasn't disappeared completely; not just yet. Amidst the rubble two small figures, young girls, travel together, scavengingwhat they need to survive as they explore the remnants of a world that they are too young to remember. It's a strange journey, but one that's filled with wonder as each new day brings another discovery, another echo of the devastated past or moment of unexpected beauty. And as long as Chito and Yuuri have each other, they have a reason to keep pressing forward. As long as there's still life, there's still hope for a future.
