Inspired by both Japanese mythology and the Nioh version.  Though in nioh its more of an ooze I went with an incorporeal undead type.

“A Yokai which emerged from thrown away needles

The Harinobo is a Yokai formed by worn-out needles and broken blades. People in Japan believed that objects used for long periods of time housed a soul within them, and called them “tsukumogami”. While these tsukumogami are not necessarily intent on harming humans, it is said that some tools harboured a grudge for being permanently discarded or being used in an improper manner, which caused them to transform into Yokai. Among them, it is thought that objects such as needles and blades are especially susceptible to becoming Yokai, so needles and blades that can no longer be used are often blessed at shrines. This ceremony is known as either hari-kuyo for needles or hamono-kuyo for blades.
