Flamme

Flamme was Frieren's master thousands of years ago. She is renowned for being the best human mage in history, and the founder of mankind's magic. Prior to Flamme, humanity considered all forms of magic to be demonic techniques.

Flamme discovers an exhausted Frieren in the debris of her destroyed village. She grew intrigued by her immense mana and adopted her under her tutelage as her disciple.
