It's been ten days since they started their "rain confinement". It keeps on raining outside.
Seems like their food is not enough. At first they thought they have stocked enough food, but they ate too much. They started to ration when they realized it, but if this goes on, their food will run out.
They could start gathering food as soon as the rain stops, but even when the rain stops for a while, it quickly starts raining again.
As we already know, water is an enemy to the yukkuri. Even if the rain stops, they can't go out until the ground dries up.
The family can only watch bitterly atthe rain that won't stop.
