An old senile male alchemist / exorcist with a genius level intellect. Being immortal (or at least 1000 years old), he has acquired much knowledge of the supernatural. Unfortunately, he forgets something he already knows if he tries to learn something new, which leads to him constantly rereading his old books and manuscripts. From Wikipedia
