Guardian

The are people from a variety of organizations who are assigned to protect and support their respective Pillar, ranging from the second to the sixth.

Overview
When one of the Eight Pillars joins the White-Clad or otherwise falls into the hands of the Evangelist, one of her followers is chosen to be their Guardian. The Guardians job is to protect their designated Pillar, even at the cost of their own life. The term is used to describe those outside the White Clad that protect and support a Pillar outside the organization.

A Guardian is chosen based on the strengths and weaknesses of their Pillar. For example, the Fifth Pillar, Inca is able to detect and ignite trace pathways of heat, allowing her to make her target burst into flames. While Inca's Guardian, Ritsu, is able to manipulate the ashes from charred corpses and use them to augment Infernals. By Ritsu's own admission, with Inca's power supporting her, she could use her ability to its fullest potential. Through cooperation and establishing a relationship, both Pillar and Guardian can work together efficiently.

The exact dynamic of each duo and their methods are unique to each pairing and can be disastrous if the pairs are suddenly changed. With Arrow acting on the behalf of her charge while they remain away from the battlefield. Meanwhile, Ritsu uses the support of her ally's abilities to use her own abilities more freely.
