White-Clad

The, identified early on as the White Hoods, are a cult organization that is lead by the Evangelist, with the ultimate goal of re-creating the Great Disaster. Using the Bugs to create artificial Infernals, they are seeking people with the Adolla Burst.

Divisions
While the exact size and structure of the White-Clad is unknown, the organisation has separate divisions. There are also members such as Haumea who do not appear to be apart of an organisational structure despite serving the Evangelist and members who are operating under cover. Known divisions include:
 * Knights of the Ashen Flame
 * Knights of the Purple Smoke

Appearance
The White-Clad have different uniforms between members and divisions, with some members having unique garbs. All of these uniforms are all white, with most featuring either the cross of the Sol God symbol or a icon of the Sun. As the name impiles, most members where a white burqa-type mask that conceals their face. Even those who do not where the veil cover their faces in some other way with things like blindfolds, masks or even long hair.

History
Members of the White-Clad have existed since the time of the Great Disaster and have been working towards the Evangelist's goals ever since. By Year 186 both Charon and Haumea were a part of the White-Clad. Following the Evangelist's predictions and orders, they were able to locate the Third Pillar and abduct him. The Third Pillar would later become the Commander of Knights of the Ashen Flame. In the Year 194, The Ashen Flame Knights were responsible for the mass Infernal outbreak in Asakusa. The following year, a member of the group was turned into an Infernal and the newly formed Company 8 responded to handle the situation by extinguishing him. A red cross was left at the scene, which was quickly taken by a company operating in Asakusa.

This included manipulating Benimaru Shinmon into attacking Company 8, before quickly escalating into a district-wide problem with citizens turning on each other. Once Arrow set the Bugs loose in the district to turn countless people into artificial Infernals, she decides to focus her attacks on Company 8.
