Sensei
An older teacher at Fujigaya Girls' Academy. She is often seen patrolling the halls, chiding the younger students for making too much noise or for running around the compound. She tries to uphold the school's prestige and dignity and the image of the school housing well-mannered young ladies. She is now a co-worker of Yamashina Hinako though she once taught her. She recognises Oono Orie immediately during the school's drama festival (in Akira's second year of high school), much to Orie's embarrassment. Sensei seems surprised that Orie looks grown up now, and Orie laments to her ex-teacher that she's now a grown woman despite her still-childish actions and looks.
