Synopsis from the japanese website (Google Translate)
"A long time ago story where there was still a gap between people and Pokemon.
On a ship heading to the Sinnoh region, Akio thinks of him when he first visited the area with his father.
"People and Pokemon cannot live together."
Young Akio was so taught by his father.
At that time, Akio met in a deep snow-covered forest with a jade-shaped Zorua.
Can humans and Pokemon really live together?"
