Jerin is another magic user for your party, but has other uses as well. As with all magic users, she should also be the one to use your items. But she can also be potent as attacker as well, as she is equiped with a bow. The bow can deal a fair amount of damage to all enemies in a group. Her magic is quite useful, especially in the final battles. Use her "mirror" spell anytime you can. This will make boss battles a whole lot easier.

Jerin is rather difficult to get, but since it is part of the story line you have to do it anyways. She is the only character that you actually have to fight for; the rest join you the first time you talk to them. the town she lives in is being terrorized by a demon, and the town is going to sacrifice her to keep it away. You find her at a Dias, where the demon takes her to a tower. After a tough battle, your party still refuses to let Jerin join. Later, however, they are forced to in order to find their way through a large forest.
