Little Witch Academia - Season 1 Episode 12

As Luna Nova prepares for their annual Samhain Festival, during which the most exemplary student is crowned the Moonlit Witch, Diana is put in charge of the committee while Akko's group is stuck playing symbolic sacrifices for an ever-sorrowful ghost. Determined to become the Moonlit Witch like Chariot was, despite everyone's low expectations of her, Akko gets pranked by a mischievous magic mirror, which turns her into an exact likeness of Diana. While initially eager to pull pranks while in this form, Akko quickly becomes aware of the responsibilities and talent Diana has, becoming dejected by the time the real Diana appears and turns her back to normal. Encouraged by Ursula to focus on what she can do instead of comparing herself to others, Akko is once again called to the Fountain of Polaris, which shows her a vision of Chariot through the perspective of one of her friends. Realising that Chariot cared more about simply bringing joy to others with her magic rather than striving to be the Moonlit Witch, Akko ends up learning a new spell.
