I have been going thought the souleater fanon for years and I have never seen a fic with maka becoming a kishin sure there a fics where they pair her with asura or crona when he/she becomes a kishin but never one where she becomes one herself so heres a challenge for you guys to take up
Here are the details if you need more info pm me
Summary
Maka hates her father for cheating on her mother and expects to go with her mother when they devoiced but when Spirit wins custardy over her she feels betrayed that she was left to her man whore of a father while her mother goes to travel the world because of this she decides to become the very thing they both hate the most, a kishin to spite them both for betraying her
Guide lines/info /what I want in the fic to be written.
This Maka will be sort of like Medusa with how manipulative she was, her weapon can still be soul but she will have to convince him to her way of thinking about not caring about people because of his condition with the sharp teeth and red eyes and helps her on her way to become a kishin with her. She cannot be allied with asura because he will see them as contenders for his power and will try to kill them, pairing can be soul/maka or crona/maka nothing else, no death the kid or black star
