『Henry Henderson』

Henry Henderson is a history teacher and the housemaster of dormitory 3, Cecile Hall at Eden Academy. Henry is a mature and noble person, who places a high importance on "elegance". To him, elegance seems to be the way a person conducts themselves, and is not afraid to correct inelegant behavior in others.

This can be seen in his interview with the Forger family: he was calm and composed even after Loid smashed the table he was sat at.
