Little Witch Academia - Season 1 Episode 15

Upon hearing that Croix and Chariot were classmates, Akko goes to Croix, who asks her to bring the Shiny Rod to her laboratory in the New Moon Tower for analysis. When Akko shows up, Croix knocks her unconscious and begins analyzing the data in her memories in order to find out how she is able to control the Rod. Fearing for Akko's safety, Ursula heads to the New Moon Tower and fights her way through Croix's defenses before confronting her. Urusula correctly deduces that Croix intends to claim the world's reconstruction magic for her own agenda, but Croix merely takes her leave, claiming how she did not gain any new information from Akko's memories anyway. After bringing Akko back to safety, Ursula explains to her about the ancient power called Grand Triskelion that is sealed away in the Arcturus Forest, and how it has the power to restore the flow of magic to the world. She reveals that the key to breaking this seal is to unlock the seven magic words hidden in the Shiny Rod, three of which Akko has already learned. Remaining unaware that Ursula and Chariot are one and the same, Akko becomes determined to find the remaining four words in the hope of meeting Chariot again.
