Lujon (ぅジョン) is a character exclusive to the 2003 anime series. He is first introduced as a struggling young doctor in his small town studying medicinal alchemy in the hopes to cure a local plague called the "Fossil Disease" and also has a connection with Lust. At one point he was discovered by Lust, who, affected by memories of her original human counterpart with her lover and Lust's own creator thanks to Lujon's physical likeness to the man, taught him more advanced forms of alchemy and gave him a fake Philosopher's Stone to help him cure his townspeople.
