So he could possibly be a level 6 then, or maybe even higher. Which is very, scary to say the least. Anyway, is there a level system for Magicians?

Sort of.

La Persona Superiore a Dio/The Person Superior to God (Yup.)
Majin/Magic Gods (Almost considered divine and can overwrite the laws set by common sense)
Sorcerers (Teachers, basically. Can handle grimoires and teach magic with them)
Magicians (Regular)

and then we have Saints and Valkyries, who are weird but should be between Majin and Sorcerer in terms of power
