Diana Cavendish
ダイアナ・キャベンディッシュ
The top student of Luna Nova who is greatly admired by her classmates and teachers alike. Hailing from Great Britain as daughter of a noble family of witches, she has a serious and arrogant nature and oftentimes clashes with Akko, whom she holds in disdain for her admiration of Shiny Chariot. She is also responsible for a few of the magical disasters that occur at the school, and usually works alongside Akko to correct them, developing a grudging respect for her persistence.
