Mahoutsukai Precure!

Synopsis

Several Magic School students decide to go with Mirai and the others to the Non-Magic World to celebrate Halloween, where their magician outfits would be passed off as costumes. As Mirai's classmates put on a crêpe stand for their town's Halloween Festival, Jun and the others end up causing trouble while using magic to try and help out, but they apologise by helping out normally and become friends with the other students. Just then, Benigio attacks with a Ghost Balloon Don-Yokubal, prompting the Cures to step in to protect the festival and the bonds between the two worlds. As the Don-Yokubal is defeated and the festival continues, Kanoko has a brief reunion with the Headmaster, while Lien looks into an old legend about citizens from different worlds becoming friends.
