Shūryō

Shūryō (Kanji: 集霊; Japanese: Soul Collectors) are a race of individuals contrived by Vulture himself, designated to the collection of souls and exorcism of ghosts.

Overview
The Shūryō are unique in that Vulture designed them in two different forms. The first of these two are Reijū (Kanji: 霊獣; Japanese: Spirit Beasts) taking the form of locusts. These locusts are not sentient, rather they act as ways for death to see and act while residing within the Spirit Realm. These locusts can move all throughout Fusō uninhibited to collect willing or trapped souls. With these, Vulture has eyes everywhere.

The second of the two are more commonly known and take the appearance of albino humanoids, making them Reijin (Kanji: 霊人; Japanese: Spirit People). Said Shūryō are afflicted with the Hanzai (Kanji: 犯罪; Japanese: Malediction), a mark over their hearts which makes them subservient to Vulture, as well as signifies their inability to move onto the next world.

Unlike their locust brethren, the humanoid Shūryō do have individuality amongst themselves, capable of free thought, speech, and the like. While they are free to act in any way they please, the Hanzai acts as a safeguard for Vulture to prevent outright rebellion. Even so, no matter the shape all Shūryō have the ability to perceive and interact with ghosts.

When an evil spirit or wandering ghost refuses to or cannot pass on and instead causes trouble, the humanoid Shūryō are sent because of their ability to fight. As such, many either join the Crimson Hunters to not only do their job but to attain freedom from the Hanzai, or exorcists in order to combat ghosts easier.
