Mirai is a 13-year-old girl who lives in the human world. One day she witnesses a mysterious object fall from the sky into the park. Excitedly, she brings her stuffed bear Mofurun with her to see what it was. When she gets there she sees a girl named Riko flying on a broom. Riko is of the same age and from the magical world. Mirai has a lot of questions, and Riko explains that she's searching for a jewel with strong powers called "Link Stone Emerald."
Then Batti, an ally of the dark magic users Dokurokushi, appears before them and demands that Riko hand over the "Link Stone Emerald," which Riko herself had been looking for. To make things worse, Batti uses dark magic to create a monster known as a Yokubaru! Mirai and Riko join hands and with the magic words "Cure-up Rapapa!" they transform into the legendary Pretty Cure.

MahouTsukai Precure is not particularly a deep or plot-centric anime. I guess it could be considered your typical magical girl series. However, that's not what I'm looking for in this series. I'm looking for a cute and enjoyable magical girl show, and I'd say this fits the bill. Some Precure fans dislike it because they say it doesn't live up to it's predecessor, and some do like it, but I can't judge it on that, as this is kind of my introduction to Precure and I can't say I'm disappointed. If you want a serious, deep mahou shoujo, then I recommend Princess Tutu or PMMM, but if you're a magical girl fan who wants an anime to pass the time, I'd say MahouTsukai is for you.read more
