Gravity Game KAMiBAKO - Mythology of Cube Switch

Story
Long ago...

Seemingly out of nowhere, the world suddenly began to fall to pieces, fragmenting into cubes. Amidst the disaster many lives were lost, and spawned from this calamity came natural disasters, decimating all land and water.
The balance of the world was offset, and people's lives were forever changed.

The disastrous phenomenon that reduces the land to cubes, what became known as the "fragmentation",
continued to spread throughout the world with no signs of stopping.

To restore the order of the world, the goddess Chroem selected an individual to fulfill the role of "Restorer", the one who would restore the lands. They were tasked to journey across the world and rebuild all that had been destroyed
