You are a young adult, born with the mark of the summoners. Like anyone your age, with such a mark, you must become a summoner. You arrive at the Academy, got introduced, and start follow class.

After a few weeks, the most decisive day of your life is unfolding before your very eyes. You get in the summoning circle, start the incantation, and are about to summon your very own familiar. Whatever it may be, you will be bound to it for the rest of your life, no refund.
