Witch Hat Atelier Episode 4 changes magic system

Episode 4 of Witch Hat Atelier reclassifies Earth magic as one of the four core magical disciplines, replacing Light magic's previous place among the big four. DoubleSama's review labels the change a retcon of the show's established magic rules and points to the episode's new emphasis on Earth-based practice. The episode foregrounds lessons and institutional worldbuilding that center Earth magic rather than Light, which reframes earlier scenes that treated Light as foundational. That shift alters which spells count as foundational and will reshape character arcs for Coco and her mentors going forward.
