Enji is a cute little android girl with cat ears and a tail. She came from a foreign country to become a student at the same school Ai goes to. Back in the country where she hails from, she has only experienced all-android schools, so this is her first time as a student in an all-human school. Ai Kodama has been assigned as “Enjigakari” meaning that Enji will have to take care of the little android girl and show her the life of a normal human.
