"ALSTO" is a world covered by sea clouds.
There are supergiant creatures called giant divine beasts, and people build their country and live in the giant divine beasts.
However, at some point the giant divine beasts reach old age and sink into the sea of clouds.
The chaos of those who lost their 寄辺 has begun to create distortion in the world.
Some human beings are capable of producing and exercising the power of the sub-species "Blade."
They are called drivers and share the weapons of Blade.
And as partners, they grow together and share their destiny.
