Enji is a cute little android girl with cat ears and a tail. She came from a foreign country, becoming a student at the same school Ai Kodama attends. 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 a mostly-human school. Kodama has been assigned to “Enji Duty”, meaning that he will have to take care of the little android girl and show her the life of a normal human.

Note: Soon after the first volume was published in 2010, the series was cancelled, leaving 9 of 18 chapters uncollected. However, in 2023, a Complete Edition was finally released, collecting all 18 chapters and adding a new bonus chapter.
