Finger Bearers
Finger Bearers are special grade cursed spirits that form when a cursed spirit consumes one of Sukuna's fingers. The process happens inside cursed wombs—essentially gestational chambers for cursed spirits—and results in creatures powerful enough to rank at the special grade level.
These entities are basically what you get when a cursed spirit gets a massive power boost from absorbing one of the King of Curses' body parts. Since Sukuna's fingers are scattered across Japan and form a central plot point in the series, Finger Bearers represent a significant threat; they're born already dangerous and tend to cause major incidents wherever they appear.
