Fullbringer
From Inga no Kusari wiki
Fullbringers are living humans who have a high enough level of reiatsu to be able to see the souls of the dead. Unlike quincy, fullbringers rarely tend to be organised into massive groups, and most of them live their lives without knowing that there are others who share the wondrous abilities they bear. Due to the fact most of them do not inherit their sight but merely gain it through chance, they are often seen as outcasts to society if they choose to speak about the things they can see that others cannot, most of them learn to hold their tongue on such things, and as they age, they gradually lose their ability as they continue to deny it. If a fullbringers practises with their sight, they may discover that they have an energy which they generate more of than normal people, learning to control and focus the reiatsu that they exude is crucial to their growth as a spiritual being.
Fullbringers who learn to control their reiatsu, focusing it through a near and dear possession, often bring out amazing abilities. As an embodiment of the fullbringer's subconscious self, it generally embodies their ideals and personality, granting them abilities that are useful and meaningful to them. Furthermore, items with less personal significance that is saturated with enough of the fullbringer's reiatsu can gain powerful abilities of their own, this is known as a glint.
