Nathan

Nathan Hunter Graves is one of the members of the Oltanis Team. He is a vampire hunter that lived in Austria that worked with the Baldwin Family, and also the Kibellicus Family. He along with Hugh Baldwin are two of Marius Kiba's trusted knights and protection for the Kibellicus Kingdom.

Nathan is a human and one of the few on the team, but he is able to cast abilities from spirit cards and magic he uses to fight.

Nathan today works at Kingdom of Marius as the right hand and while he isn't one of the most seen of the Oltanis Team members, he does lend a hand when he can. Since he works for Cerberus before Marius became king, he wasn't able to take on many missions for the Oltanis Team, but when it comes to protecting his family, he will be one of the first to fight off evil.
