北条 沙都子 Hōjō Satoko
Satoko has a very energetic and mischievous personality despite the suffering in her past. Both of her parents died, her brother disappeared, and she was abused by her aunt and uncle. Irie, Satoko’s doctor, suggests later in the series that Satoko killed her parents herself as they had a bad relationship and felt threatened.
Satoko is the only person to ever fully recover from the last stage of the syndrome, though she has to take shots regularly to keep from relapsing. She is also color blind.
