On the way back home, Ryota and his sister Aya met an abandoned Shiba Inu.

They immediately went to the emergency shelter, where they heard that Yamakoshi became isolated after the earthquake, thereby making it hard for rescuers.

Subsequently, rescuers from the Japan Self-Defense Forces started combing the village and evacuating people by helicopter.

Her rescuer reluctantly refuses this request, and seeing her pain at being separated from the dog, he felt extremely bad.

Without her owner, Mari tries all ways and means to protect her puppies and feed them properly.

One day, Aya read in a newspaper that torrential rain would soon flood Yamakoshi and became worried about Mari.

She convinces Ryota to sneak into the disaster zone in order to rescue Mari.

When the aftershocks subsided, each family was able to send one representative to go into the village to survey the damage and to collect personal items.
