Magika Swordsman and Summoner, Vol. 01

When humanity discovered an alternate dimension filled with magical and mythical beings, the world as we knew it would never be the same. Humanity soon learned to harness these extra-dimensional forces and summon mystical beings into their midst through the power of 'summoners'. Years later, fifteen-year-old Kazuki Hayashizaki is chosen to be the first male summoner. His attendance at an all-female summoner school is met with much opposition, especially from his sister, a magical swordsman whose task is to guard summoners.
