One night, a girl named Mirai Asahina spots something strange landing in the park nearby. The next day, Mirai receives a pendant from her mother before going with her teddy bear Mofurun to investigate the park. There, she happens to meet a magician named Riko, whose identical pendant react with Mirai's when she tries to fly away. Just as the two girls get to know each other, they are approached by Batty, an emissary of the evil Dokuroxy, who is searching for something known as the Linkle Stone Emerald. As Mirai and Riko try to escape, Batty transforms a dump truck into a monster known as Yokubal to chase after them. When Mirai and Riko try chanting a spell to make the Yokubal go away, their pendants suddenly transform into Diamond Linkle Stones, giving them the power to transform into the Witchy Precure Pretty Cures, Cure Miracle and Cure Magical. After managing to drive Batty away and discovering that Mofurun had come to life in the process, Riko, hoping to find out more information, brings Mirai with her to the Magical World to take her to the Magic School she studies at.
