Nathan is a priest who has travelled to preach the teachings of the Harvest Goddess. Nathan and the nun Alisa will move onto the Mystical Islands after they have been raised, and will live in the church.
He adopted Alisa after her parents died, and is a kind and gentle soul. He is always willing to listen to anybody who is having troubles, but he doesn't have a weekly church service. He never leaves the church, and so he is always easy to find.
