This title and this series are remarkably similar to each other. Almost to the point of just swaping characters in some cases. The story and settings are similar and the characters are almost literaly the same archytypes. Even the characters powers particularly the main characters are almost the same. If you enjoy this series you will like the other and vice versa since its pretty much the same scenario except told by a differant storyteller.
One night, Madoka has a terrible nightmare – against the backdrop of a desolate landscape, she watches a magical girl battle a terrifying creature, and lose. The next day, the teen's dream becomes reality when the girl – Homura – arrives at Mitakihara Middle School as a transfer student, mysteriously warning Madoka to stay just the way she is. But when she and her best friend Miki are pulled into a twisted illusion world and meet a magical creature named Kyubey, the pair discovers that magical girls are real, and what's more, they can choose to become one. All they must do is sign a contract with Kyubey and agree to fight witches that spread despair to the human world, and in return they will be granted a single wish. However, as Homura's omen suggests, there's far more to becoming a magical girl than Madoka and Miki realize...
Both involve ordinary person taken into world of magic and power to grant one wish. These series might not look so similiar on the first glance but after digging deeper into the storyline similarity is stunning.
