Futari wa Pretty Cure/WMG

Futari wa Pretty Cure is set in the same universe as Mahou Sensei Negima

Evidence: Nagisa and Honoka appearing at the Mahora Festival in the fourth panel. How did they end there? Well, after the Dark King attacked Earth directly the mages finally tracked the Pretty Cures, and to keep The Masquerade offered them a scholarship and training in Mahora. It would also explain how they became able to one-shot a Zakenna in the All Stars movies: the training paid off.
