|Episode 15 - Chariot of Fire|
Diana is researching who Croix is... Ursula shows up and she talks about how she knew Croix as a student, but then backs off when Diana asks for more information... Diana then tries to look up info on Ursula...
Ursula fears that Croix must be after the revived Claiomh Solais (aka Akko's Shiny Rod).
Akko is totally a fan of Croix now, but other students don't like this idea of magic becoming more like science...
That older teacher who is against Croix's modern magic, says she used to be a fan of Croix... While Chariot was bad at her studies and wasted the school's magic doing performance art, Croix studied and worked hard to try to bring magic to the modern age... but now she's bringing too much science to the academy... Making everyone use phones and tablets and stuff...
Akko talks to Croix about Chariot, and Akko is surprised that Croix thinks highly of her. She then convinces Akko to bring the rod she found in Arcturus forest to the New Moon Tower, where Croix's lab is set up... I think that's also where the sorcerer's stone is.
When Ursula finds out where Akko is, she starts rushing for the tower... Croix starts scanning the rod and Akko, trying to figure out how she uses the rod's power... She sees that Chariot is approaching, and the tower's defense system kicks in. Ursula goes through this intense action sequence while climbing the tower... her hair turns red and she looks more like Chariot now... Ursula/Chariot confronts Croix and rescues Akko, but Croix has already gotten what he needed out of her.
After Akko wakes up, Ursula tells Akko the origin of the Shiny Rod... it's from 10'000 years ago, when Yggdrasil was still filling the earth with infinite magic... Yggdrasil's branches even held the stars and planets together... but the witches used up so much of its magic, that it eventually whithered. The original power of the Yggdrasil, the Grand Triskelion, was sealed within Arcturus by the Nine Olde Witches... only the revival of the seven words can break the seal.
Akko realizes that Chariot must've been trying to revive the seven words this whole time... She says she'll revive the rest of the seven words and meet Chariot.
