The twist in 2004 shocked audiences: Tsumugi is not real. Not in the Sixth Sense way, but in a metaphysical sense. She is a Tsukumogami —a tool that has acquired a spirit. Specifically, she is the spirit of an unfinished tsumugi obi (sash) that Kazuki’s grandmother was weaving in 1978 when she died of a stroke. The "illness" Tsumugi suffers is the obi unraveling thread by thread.

The keyword is often searched alongside the phrase "why does it hurt so much?" The narrative structure is a time-loop disguised as a memory game. Kazuki relives the same 31 days of October repeatedly, trying to prevent Tsumugi from wandering into the forbidden Silk Repository—a building where the village used to store silkworm eggs, now contaminated by a historical chemical leak.
