ゲルダ

A courageous and firm individual. Her tone and behavior are not overly flighty, and she appears to be relatively sane. She is very skeptical of Paradise and its medical staff, but she sometimes states that she is "not Gerda", which suggests that her Fairytale Syndrome may be on the mend. She is haunted by a strong desire to find "Kai", a figure whose face she has forgotten. [translated from official website]
