Black monk emerging from the darkness of a Buddhist altar
Nuribotoke
The altar doors open though no hand touches them. Only the hanging eyes of the black monk stare at the dust-covered memorial tablets.
Overview
Nuribotoke is a classical yokai known for its black monk-like body and drooping eyeballs. Edo-period scrolls and Sekien's books show the image, but no original explanatory text survives, leaving the picture itself to carry the unease.
Encounter
It appears from old Buddhist altars or dark rooms. In Sekien's image it leans out from the altar, making a place of prayer and ancestral care feel suddenly occupied by something alien.
Lore
Nuribotoke is drawn in Sawaki Sushi's Hyakkai Zukan and Toriyama Sekien's Gazu Hyakki Yagyo. The early sources preserve mainly name and image; later meanings tied to altars or tool spirits are largely interpretation.
Traits
Its body is black, and both eyeballs hang from their sockets. It appears silently near neglected Buddhist objects, moving little but freezing the viewer with the pressure of its gaze.
