Magi

The word "mage" originally referred to a "user of magic."

Using an alchemical process only privy to SAURU, the ritual creates the physical body of the 'serpent' then links it to the candidate girl through covenant magic. If successful, she will become the leviathan's partner, in other words, a mage.

But in modern times, the most outstanding magic practitioners were leviathan covenantees. Hence, referring to them as "magi" became spontaneously entrenched.

Making use of their power for public benefit, magi became the protectors of human settlements.

Witches—magi—were precious talents. There were probably fewer than a hundred and fifty of them in the entire world.

Among them, the majority belonged in the range of Level 1 to Level 3, but witches reaching Level 4 or above, designated "master-class" by SAURU, were extremely rare. There were only eight Level 5 witches in the entire world.
