My Blind Familiar: The Sword Devil

Familiar, a magical creature of any kind that a mage channels mana through to perform magic or tasks. Familiars are all different and each mage can have only 1 and it can only be summoned in Magic Academy due to the preparation for this being in these locations.
The age that these students obtain this is when they start their second year in the magic academy. The first year was purely to teach the students how to gather mana and improve their capacity as well as to weed out those without talent for gathering mana. The entire year teaches the students breathing techniques, meditation and teaches the basis of how magic works.

With a year of training, the young man has gone from the weakest to one of the strongest with his evolved familiar, A Sword Devil.
