Fullbring is a special ability by which certain Humans, whose parents were attacked by Hollows before they were born, possess. It allows them to manipulate the "soul" of matter for a variety of effects, such as using a drink's "soul" to have it help them drink it, or, if they have a particular affinity to an object, then Fullbring can be used to alter the objects form. For example, Kūgo Ginjō can change his necklace with a cross-shaped medallion into a large sword.
