Seraph

A Seraph is a high-class archangel with divine powers. They reside in the human world of Valero and rule over their respective nation there. However, there are some Seraphim in the world who do not oversee any nations and rather wander around the world without duties. Seraphim are the divine counterparts of Sins.

Overview
Seraphim attain power based on how much faith the people have in them. Each of the Seven Seraphim has an ability unique to them. With their amounted faith, Seraphim can access their Divine Dress, a transformation that allows them to attain their full-angelic forms. With their activated Divine Dress, they can access their designated weapon called a Saint.

Seven Celestial Seraphim
In the human world, there are Seven Seraphim sent from Coelum who descended to govern the seven nations that make up Valero as well as maintain the faith and beliefs of the people who occupy these nations.

Each of the seven Seraphim completely constructed their own nations and spend their time in their holy building called a Sanctum.
