Fullbring

is a technique utilized by the Humans in the group Xcution.

Overview
Fullbring is a special ability which certain Humans are born with. There seem to be two levels to the manipulation of "souls" 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 a personal Fullbring can be used to alter the objects form or condition. For example, Kūgo Ginjō can change his necklace with a cross-shaped medallion into a great broadsword. Every Human user of Fullbring has a parent who was attacked by a Hollow before they were born. Traces of the Hollows' powers remained in their mothers' bodies, which were passed on to them when they were born. Thus the powers are closer to those of Hollows than they are to those of Shinigami.
