/**
Tsukumogami (付喪神) is the collective name given to a type of yōkai (Japanese spirits or monsters) which are haunted household objects. It’s a Shinto belief that everything has a spirit, so in Japanese folklore it’s possible for inanimate objects to become sentient. The transformation occurs on their one-hundredth birthday, as only after serving people for a century can objects gain souls.
