Harry Potter: Magical Girl Harry

"Make a contract with me and become a magical girl!" "Can all the wishes I make really come true?" "That's right. You're the most powerful, so any wish you make can come true. Now, tell me your wish!" A boy who survived a great disaster, no, a girl who survived a great disaster, made a contract with Kyubey by chance and officially became a magical girl. "I never thought there would be a girl in this world with talent as great as Kaname Madoka's." "It's just a shame that the girl named Kaname Madoka died fighting what appeared to be the most powerful witch." As the savior of the magical world, she bears its future on her shoulders, surrounded by countless threads of causality. This is one of the timelines in which Homura Akemi failed to save Kaname Madoka. After Madoka's death made it impossible for Kyubey to achieve its goal of gathering energy, it happened upon the savior of the magical world by chance and brought her into the world of magical girls. This is that story.
