A one-shot story about the loss of a loved one.
Tsukumogami: In Japanese folklore, tsukumogami (付喪神 or つくも神, lit. "tool kami") are tools that have acquired a kami or spirit. Because the term has been applied to several different concepts in Japanese folklore, there remains some confusion as to what the term actually means. Today, the term is generally understood to be applied to virtually any object "that has reached its 100th birthday and thus become alive and self-aware", though this definition is not without controversy.
