Alter Ego is a friendly AI whose personality resembles that of Chihiro, their creator. When portraying another person, Alter Ego can change their personality to fit that person. They refer to Chihiro as 'master'. They also seem to have some form of "determination", evident when Alter Ego still wishes to help also showing bravery as they are unconcerned for their safety when it comes to helping others despite knowing the danger. Very kind and cheerful.
