The protagonist went to a certain region for utilizing his long vacation.
It was a small town situated between the sea and mountains.
While it had not been mentioned in the sightseeing guidebook, despite being small hot spring village, it seemed to have taken the world by storm.
But along the path, trying to avoid colliding with a "stray dog", the protagonist's car crashed into the guardrail.
Although somehow crawled out of the wrecked car, pain kept rushing within the whole body.
I wonder if I will die like this... While watching the blue sky, an innocent voice of a girl reached the protagonist's ears.

"Are you alright, doggy? Miya will save you!"

But that encounter was the beginning of an extraordinary unprecedented experience...
