Mahou Shoujo Anime is, from what I researched, not a thing I watch. It's about magical girls? Like Sailor Moon, or something. The closest I get is maybe Ai Enma, Hellgirl, from the Hellgirl series. I am sort of confused by the definition of Mahou Shoujo, so I'm just gonna assume that this counts.
Here is my defense:
1. She's a girl.
2. She has magical hell powers.
3. She wears a school uniform that looks kinda like sailor moon's.
