Tokikawa, a young hunter, is trapped in an endless time loop - every dawn, he wakes up in a deserted and lonely city, and the identities of the prey and the hunter are constantly changing. The world collapsed, but Shichuan could not die and could only find the key to escape in the fragmented time. His prey is not living creatures, but "my yesterday's self" - every round of hunting is a life-and-death confrontation with memory, self and destiny. Tokikawa longed to break away from the cycle, but found that only by defeating the deepest shadow in his heart could he tear apart the cage of time. The novel uses a confusing time and space structure and cold psychological description to show the collapse and rebirth of a young man in self-hunting and infinite reincarnation. There is no savior here, only the loneliest hunter, swimming upstream, desperately chasing the only tomorrow that belongs to him.
