Summoner

Gryff never knew he was the most powerful summoner in the world until a rogue monster attacked his village. Now, he's been recruited into the top magical academy, beautiful women are breaking down his dorm-room door, and the headmaster has big, big plans for him. Instead of summoners being maligned by society, Gryff is in a position to make them revered and honored. There's just one problem: The most powerful fire mage in the academy wants to protect the status quo and will do anything to stop him. This novel has harem elements.
