In the nomadic world of the sea of clouds, humans live on the backs of floating giant beasts called "cloud whales", and their gender changes with the seasons. Cangliu, a retired god-slayer, is burdened with the curse of eternal life. He is suffering from endless wakefulness and accumulated pain. His only desire is to find the true method of death. When the wayward god "The Jester" begins randomly destroying a floating city every hour, Aoi is forced to end his seclusion and embark on a journey against Discord. However, in the process of pursuing liberation, he gradually uncovered the shocking truth: the collapse of the world's laws actually originated from his own God-killing blow. Now, the key to curing the eternal curse may be in the hands of him, the unintentional creator - to end himself, or to reshape the world?
