A device that allows people to stop growing during long slumber, traveling to the distant future. The so-called time machine produced by Winter Chapter is ultimately revealed to be a cryogenic sleep device; Chena mistakenly thought he had returned to the past, but in reality, after the world's climate and civilization had gone through cycles, a similar summer had appeared again.
Amnesia and Text Inside the Device (PS4)
According to the PS4 version, cryosleep has the side effect of memory loss. By the Mafuyu arc, Kirina saw the repeated names "せつな" and "りんね" inside the device, and managed to preserve her memory from these traces.
