Five years ago, he was a member of the Computer Rescue Center and a radiologist at St. Thomas University Hospital. However, due to his excessive gaming addiction, he caused the death of a patient. He subsequently left in anger and lost his medical license. For unknown reasons, his hair color has changed from black five years ago to partially white hair. He has a low food preference and, when asked about his favorite food, he would say, "I'll eat anything I can."
