This is the only name I can think of while making it but I want a catcher name sorry lol. In a world where Magical "girls" and "witches" work together not a friends but a wielders and weapons. It would only be a logical conclusion that sometimes they just don't click!! Join a witch by the name Sage as she tries her darnedest not to be dragged into all this friendship is magic bull. She knows what she's here for and it ain't to help no frilly fru fru girl to praise the moon or whatever. No she's here to rule the multi-verse. So why is it that she's been roped into a job for it!!

Tldr; A Madoka Magica/ Soul Eater mash-up but some witches are captured and work off their corruption as magical "girls" weapons.
