Love Sickness

Love Sickness is a particular disease that seems to be contracted by the empresses of the Kuja tribe. This happens when they fall in love with a man. If they suppress their emotions, then it weakens them and eventually lead them to death. However, if they accept their emotions and follow the loved one, then they will be fine. This disease killed many Kuja empresses in the past. It is unknown if the illness can be contracted by normal Kuja citizens.
