The town of Hinasaki was still covered by an unmoving barrier.
The barrier was created by the Sengawa family, who had built a small financial empire based in Hinasaki, with the hope of prospering.
However, it was considered too large to be activated by human power alone, and many years were thought to be needed before it could be operational.
The boy, Tetsu Kurashiki, who had lost his memory, was discharged from the hospital and began his recuperation at home.
In a house where he had no memories of the past or the life he once lived, he still tried to live each day positively.
During his aimless days, he encountered the practitioner Yūri Mutsumi, which allowed him to glimpse an unreal world.
He never imagined that this was not a temporary occurrence, and that it would soon come crashing down upon him.
With memories that would not return, strong regrets, dreams of a white moon, conflicts among practitioners, and a crisis threatening the survival of the world,
as various schemes intersect in the town of Hinasaki, the story of the "Hina no Ame" progresses, focusing on the boy, Tetsu Kurashiki.
