Ten Great Saints

Ten Great Saints are the paladins or holy knights at the top of the organization known as the Western Holy Church. Only the strongest soldiers can enter the group, and their hierarchy is decided by strength and ability. As the name suggests, being an Enlightened is a minimum prerequisite, and it is expected for the members to continue to improve themselves so they can attain Saint and even Hero level.

With the death of Garde and defection of the Three Sage Warriors, the Ten Great Saints is practically defunct. However, most of the Crusaders are still active in service.

History
Originally created by Luminous Valentine as a division of the general forces among the paladins, she hand picked the strongest fighters with the greatest potential for evolution with the intention of encouraging the creation of Heroes under her command. The role of the Clerics of the Seven Luminaries or Seven Luminaries for short, on the other hand, was to act as mentors to train this potential to the fullest.

Organization
The Church is further subdivided into two big groups: the Crusaders or Templars, paladins under the direct command of Hinata Sakaguchi and the Pope's Imperial Guards, under the direct command of the Holy Emperor. The line between the two is blurry, especially as the Holy Emperor tends to not give any orders that would interfere with the Templars.

To further prevent misunderstandings and friction, a meeting is held once a month between all members of the group to discuss events and clarify actions.

Hinata Sakaguchi being the strongest fighter not only held the title of Captain of the Paladins, but also defeated Saare and taken his title as Head Knight of the Pope's Imperial Guard. This makes her the indisputable leader of both subdivisions, effectively unifying both groups as long as she is in charge.
