Puella Magi Madoka Magica

In a city torn apart by chaos, 14-year-old Madoka Kaname wakes up from a nightmare where she sees a girl bravely battling a terrifying creature. A quirky cat-like being named Kyubey pops into her dream, insisting that the only way to change this dark future is for Madoka to become a magical girl by signing a contract with him. The next day, she meets a mysterious transfer student named Homura, who warns her to stay normal. But when Madoka and her best friend Sayaka encounter Kyubey, they learn that magical girls are very real—and so are the ominous dangers that come with that power.
