Diana Cavendish is one of the older girls at Luna Nova Magical Academy. She is known for being very proficient at magic. And finds herself running along adventures with Akko Kagari (the main character). Diana is a classic Tsundere type character who starts out as a “rival” to Akko, but later becomes close to Akko with a hint of possibly having a relationship with her whether as friends or a little more. Of course in these adventures she’s 18+ as are all of the characters involved.
