This is the sorrowful tale that takes place in the town where the sun never rises, Shangri-La. A girl known as the the saviour of the town — the ‘Usotsuki’ * — and a group of young men, each with their own assigned roles, must learn to forgive each other’s lies……
On a certain day in the year Heisei xx, a total solar eclipse occurs. A young girl, who has lived her whole life in solitude until today, notices that a moon, shining blue, is reflected in the lake. She peers over…and falls.
When she next opens her eyes, she finds herself in the town of Shangri-La.
Standing beneath a full moon glowing a radiant blue, the heroine is attacked by a group of men who seem to have lost all reason. It is then that she is rescued by the ‘Brothers of Calamity’ (災禍の兄弟・saika no kyoudai), three young men who are scorned by the town’s people as people who will bring forth the demise of their world.
Even in Shangri-La, the moon continues to wax and wane, mysteriously affecting the mental states of its townspeople as it does so. Everyone strongly believes that the heroine is the ‘Usotsuki’ who will save their world, but……?
