Barbara and Hannah appear for the first time next to Diana, making fun of Akko saying that she is childish for admiring Shiny Chariot. Later in the flight class, Hannah says that Akko is pathetic for not knowing how to handle a broom.
During the treasure quest in the academy dungeons, Barbara and Hannah are very frightened to have to help Diana with defeating gigantic monsters, and suggest that they return to the class with the treasures that they already have. Diana refuses and decides to find truly rare treasures. They warn her that there is a minotaur behind her, which is defeated by Sucy, who just got there along with Akko and Lotte, with her venomous and highly corrosive potion. Due to Diana's insistence on finding rare treasures, she decides to go down the large hole made by the potion, but both think it would be very dangerous. Diana replies that if they are so afraid, they should stay with Akko and her friends. Both follow Diana into the hole, not wanting to stay behind with them.
They explore the cave below and find an iron maiden. Diana decides to open it, and releases the Ancient Dragon. Upon seeing its size, Barbara and Hannah mock it and cast offensive spells, causing it to grow in size. Diana realizes it's feeding on their magic, but before she can tell them to stop, the dragon attacks and Diana, Hannah, and Barbara come out of a hole that the dragon made. Diana takes their brooms and fuses them with her own broom to create a faster version. Both are last seen flying together on brooms with other witches alongside Akko and Diana.
In The Enchanted Parade, Barbara and Hannah appear at the beginning during Professor Finnelan's class, praising Diana for solving the chaos caused by Akko and Sucy, and for her perfect use of Luna Lana. After Akko and her friends finish the choreography practice, Barbara and Hannah enter the room with Diana, and make fun of their Happy Time Project, saying that it's very childish.
Barbara and Hannah first appear with Avery, talking about Luna Nova's status before aboarding the Ley Lines. They are then approached by Akko, who, unaware of the Ley Lines, asks them about the train station. Amused by her lack of knowledge, they explain her about the Ley Lines, before entering the station with a smug look in their faces, without helping her. They later appear during the opening ceremony of the academy with Diana.
Barbara and Hannah appear in a similar way to Akko as in the first OVA. In addition, they speak for Diana saying that she comes from a rich and famous family of wizards.
Barbara and Hannah are Diana's companions in the broom relay race, the latter acting as the leader.
Barbara and Hannah go to the city during their free time. Realizing there was a Night Fall event going on, Barbara convinces Hannah to join it with her, under the pretense that they'll just watch the "losers". Barbara tries participating in the pop quiz, but is shamed by Hannah for it. After realizing Akko and co. were in the event, they denounce them to Finnelan, who gives them a punishment after they're back to Luna Nova, adding to the one they had already received.
