Gim Cookie is an exorcist who resides high in the mountains along with the Spirit Tree. His main job is to get rid of and banish ghouls, goblins, monsters, and the like- he mostly achieves this using various talismans that have different effects. While he's quick to help anyone in need, most of the time he tends to be lazy and sleep-deprived, preferring to stay in the mountains to rest. He's very knowledgeable on spirits and other beings, although he can also be tricked very easily.
