Ebata

A secretary serving the Nakano father. A middle-aged man with white hair. He has been in his current position since before the five sisters were taken in by the Nakano family, but he was a teacher before that. In the winter of their second year, when Fuutarou felt inadequate and voluntarily quit as the five sisters' tutor, he listened to the sisters' request to oppose this and cooperated in a plan to have Fuutarou continue as their tutor.
