Adrift in a seemingly endless sea of sand, the people of the ‘Mud Whale’ live and die on their ship-like island with no knowledge of how their existence began. The elders of the society know more than they let on however, and when a mysterious girl is found on a passing piece of land they begin to ask her questions related to the ‘mainland’. Overhearing this, the young archivist Chakuro realizes that she just might be the key to unlock the mystery surrounding his world.
A mystery-tinged drama focused on the trials and tribulations of a small isolated community. Though it becomes a war drama for a while, the majority of the focus is on social conflicts.
