Starry Sky: In a time following a massive war, two girls, Chito and Yuuri, travel aimlessly through a dark abandoned factory in their Kettenkrad. After Yuuri slobbers all over her hand during her sleep, Chito realizes that they can use a wet finger to find a way out by feeling the direction of the breeze and they emerge to see a starry sky.
War: The next day, the girls explore a battlefield from the apocalyptic war and come across an abandoned plane. They find explosives and rations. Surprisingly, Yuuri pulls her gun on Chito and demands the last piece in a ration pack.
