A maid of the Arima household who sometimes councils Teppei. She had been in an orphanage from a very tender age until Isshin Arima took her in his care and brought her up to be an admirable maid. She has sworn to serve the Arima family to show her gratitude. She feels being privileged to be assigned as the maid-in-charge to serve Teppei, the next heir to the Arima Group.
