TSUKUMOGAMI
Lore
Typically, when speaking of monsters, one begins by describing their appearance or recounting a dramatic tale. Yet in this case, we start with some general observations before delving into the most fascinating members of this uncanny group. We are dealing with old objects-very old, in fact.
Tsukumogami are "spirited" items that develop awareness and will after 100 years of existence. No one truly knows the precise mechanism: perhaps they absorb magic or energy across a century, or maybe they simply grow tired of being mundane and decide to rebel.
Practically anything can become such a yokai. Ancient Buddhist texts, with their notion of "all beings suffer," suggested that even inanimate objects experience emotion. Hence the belief that discarded or neglected items might return as vengeful spirits. Some attribute this phenomenon to tsukimono-wandering spirits that can inhabit objects.
Over time, a tool or ornament, deeply infused with a user's energy, may gain a sort of soul. And indeed, how you treated that item could determine its disposition: a polished sword might transform into a benevolent entity, while a threadbare kimono you flung into a dusty corner could come back brimming with spite.
