見習いの魔法使い・ココは「普通の人は、本来魔法使いにはなれない」という重圧を日に日に感じるようになります。一方、師匠のキーフリーは「つばあり帽」に異常な執着を見せ始め……。

Cast yourself into the world of witches as Qifrey chases after the dark mysteries of the Brimmed Caps! With some quick thinking and ingenuity, Coco and her fellow classmates use their growing magic skills to save some locals from a grim fate. But this triumph nearly turns to tragedy as the Knights Moralis threaten the young witches with severe punishment for disturbing the natural order of magic. Qifrey convinces the Knights to overlook this issue, but a peculiar happening related to this incident puts him onto the trail of the same forbidden magic that brought Coco into his atelier. This may be Qifrey's only chance to come into contact with the Brimmed Caps, but is he in over his head to engage in this treacherous pursuit on his own?
