Tsukugami

Tsukugami are a peculiar breed of Yokai that arise from ordinary, inanimate objects that have lasted for one hundred years.
== Biology ==
Tsukugami have biology more similar to that of a golem than of an organic creature. Their body is primarily composed of whatever materials their original object crafted from; however, these materials will have increased flexibility that allows for the Tsukugami to locomote through anomalous means. Tsukugami body structure is as varied as any crafter can imagine as all manner of objects can become one, but there are some mutations that arise in many Tsukugami that give them uniformity. One such mutation is the development of a single eye and mouth at their center of mass. Another such mutation, albeit one that is less common, is the development of limbs, either arms or legs, in places where they might be expected based on the size and shape of their body. These limbs will often appear to be either humanoid or bestial in nature, but regardless of any superficial aspects they may acquire, they are always made of the same material as whatever part of the object the base of them is attached to. 
Tsukugami do not need to consume organic matter in order to survive, but they do need to consume materials akin to the ones that they are made from in order for them to operate at full strength and to naturally regenerate any wounds they may receive. A Tsukugami that is starving will never succumb to starvation, but they may be immobilized from weakness and need to be manually fed by another creature. Tsukugami that do not have mouths will need to either insert their "food" into a natural body aperture or otherwise envelope it in order to consume it.
== Awakening ==
While the mechanics behind Tsukugami awaking are vague, it appears that they can arise from objects that do not hold significant sentimental value but have lasted through one hundred years of use by Ib. For example, a very valuable jade heirloom teapot that is used in weekly tea ceremonies will never awaken as a Tsukugami, but a regular old iron one that is used here and then will almost certainly awaken once it has reached one hundred years of age. Similarly, and wooden chair sitting in an abandoned shed for a century is very unlikely to awaken, but one that was well used and well worn for most of its life and then stored away and forgotten for a few years may very well awaken. 
== Variants ==
=== Ningyou ===
Ningyou are powerful Tsukugami that arise from dolls and puppets.
