The Heirs

In ancient times demons ran rampant, killing everything in sight. Until humans sealed them away. One century later they developed the ability to summon and control them in weaker forms. These people are known as "Summoners". Generations later, summoners learned how to manipulate the demonic elements of the demons; this caused the world to be split into four factions, each with their own element. The fire clan, water clan, wind clan, and earth clan. We now follow the story of a young boy named Jinsei Ito from the wind clan, and a princess Aiko Murasakino, from the fire clan. They've been accepted into the infamous Summoner Academy, where summoners from every clan attend and learn the ways of the summoners.
