Lujon

Lujon is a doctor in his town. He was given a Philosopher's Stone to cure his town of a disease know as "Fossil Disease". However, as the stone slowly begins to fading, he flees in search of a new stone. Later on, he meets Lust, who fixes his stone. Near the end of the only episode he was alive for(episode 35), we find out that he is engaged to Lydia(the woman that Edward Elric rescued earlier in the episode from bandits) though he is in love with the Homunculus who gave him the pseudo Philosopher's Stone, Lust.
