Master Biblia

Master Biblia is a Paladin-Class mage and is the headmaster who presides over the Biblia Magic Academy.

Personality
Master Biblia is a very intelligent and cunning man, who has a very over the top personality.

Despite being a pervert on Arata's level, he is also surprisingly keen and rational under his facade of stupidity, and appears to fully recognize the dangers facing him and his Academy on a regular basis.

Appearance
Master Biblia is a tall slender man with long pale hair that he wears in a pony tail, and red eyes. He is always seen with glasses and a coat and uniform.

Abilities
As one of the few Paladin-Class Mages in existence, the principal of Biblia Academy is rightly deemed one of the most powerful beings in the series proper, when faced with Liber's master, another Paladin, the whole reason neither of them fought each other wasn't out of laziness or compassion, but the sheer understanding that a clash between two Paladins would put the world itself at risk.

The one time he has been seen in battle, Master Biblia is shown to be able to use almost any type of magic as long as he can move his mouth, meaning he doesn't need to endure long preparations for his spellcraft or even move around the battlefield. He can also perform healing spells and is capable of restoring the entire Academy to its original form after completely being destroyed.

Grimoire

 * Solomon's Gate - The principal's grimoire, Solomon's Gate, appears as a massive doorway or book-like structure to his back, fortunately it's invisible to most, but those who reach the level where they can perceive it are likely to be driven to insanity by it. Even Lieselotte Sherlock, one of the stronger members of the Trinity Seven and at the time a Magic King Candidate, was visibly afraid of it.
