A tsukumogami (付喪神) is a type of youkai produced from a tool or object inhabited by a god or a spirit. In Japanese legend, all types of tsukumogami gain life and sentience on the 100th anniversary of their creation, and can range from harmless and friendly beings to horrifying vengeful spirits, depending on how they were treated and used. It is also said that modern electric items cannot become tsukumogami. It is unclear on how tsukumogami are treated in the Len'en Project. The only clear example thus far is Mitsumo.
Types of Tsukumogami
This lists the types of Tsukumogami that appear in Len'en.
Ungaikyou (雲外鏡, lit. "mirror beyond the clouds") are mirrors that have existed for over a hundred years and became a youkai. They are said to have the power to show humans the image of a youkai they could become, or control other youkai that have looked into the mirror.
The burabura (不落不落／不落々々 lit. "unfalling") is a paper lantern that has become a youkai. Typically considered to be a type of Paper Lantern Ghost (提灯お化け Chōchin-obake), a burabura is depicted to have a single mouth and an eye, and is tied to a bamboo stick. They are sometimes considered to be the same as Kitsunebi (狐火 lit. fox fire), which are atmospheric ghost lights said to be the creation or disguise of Youkai foxes.
