Hiraga Saito, is a boy who lives everyday the same as usual. Stumbling across a portal in the street, he found himself transported to another world, arriving in the middle of a summoning test to find that not only that magic exists, but he’s landed himself a job as a familiar to Louise Valliere; a mage who has yet to successfully cast a spell. However, not only is Saito from the modern world, he also has the markings of Gandalfr, said to be able to wield any weapon with deadly effect.
