Rem's appearance is quite skeletal, with long, spinal cord-like arms and bone-like skin. Her features, such as her hair and the markings on her face, are detailed with a light-blue shade. The only exception for this is in the anime, where these details are purple. All other media, such as the movies and games, have the details as blue.Rem "supposedly" experiences difficulty while writing the Japanese language. She is even willing to sacrifice her life to defend you. Rem is kind and protecting.
