Madoka Magica OC: Natsuki Mori

Did it. Made the contract. ／人◕ ‿‿ ◕人＼

Personality: (In the beginning) More sassy and sarcastic than kind, she will always try to find a joke out of everything. However, she just tries to lighten the mood while witch hunting, especially when her friends seem like they'll fall into despair. This shows that she's very supportive of her comrades. By herself, she is more aware of her situation and realistic about outcomes of fights. The one who enjoys puns the most.
Wish: I wish I could travel the world!
Enhanced stat and abilities from wish: Super-human speed.
Weapon: Halberd
Witch form: Mephisto.
Type: Witch of freedom.
Story:
Her Beginning: She is originally from Kazamino, the neighboring town of Mitakihara. Natsuki and her parents never got to properly bond together, since her parents tend to travel abroad constantly. She stayed with many different family members while they were gone. When her loneliness finally rises to a new level, she becomes under the influence of a witch's kiss. However, she is saved by Shiori Usagi, a Magical Girl. After becoming friends with Shiori, Natsuki is given the option by Kyuubey of also becoming a Magical Girl. Feeling a need to connect with her parents and thinking she could defeat more witches and become a "Magical Heroine", Natsuki decides to make her wish to be able to travel all over the world. The contract is made and her new life as a Magical Girl along side Shiori begins...
Her Revenge: After searching so very far, Natsuki caught up with her family all the way in London. They all spend a good while together as a family and Natsuki couldn't be happier. However, on the flight home, an incredible storm hit the plane, causing it to crash. Natsuki was the only survivor (Magical Girls completely die only when their Soul Gems are destroyed.) Nastuki was so upset and desperate from the loss of her parents. Kyuubey enters the scene and Natsuki pleads with him to revive them (he is an extra-terrestrial creature who can make miracles happen after all.) Kyuubey admits that he cannot and explains why the plane really crashed. The huge storm formed because of the distortion from making the contract. In the end, Natsuki's wish was the reason her parents died. And Kyuubey knew it would happen from the start. Natsuki, furious with this realization and deception, vowed to destroy witches and Incubators alike everywhere in the world so that they would never deceive anyone else again.
Her Demise: Natsuki never came back home to Kazamina and fought continuously, running only on her remaining hope and her hatred. Day by day, her efforts would seem futile. And they eventually were. Her hatred and sorrow finally swallowed her up. Natsuki gave into despair and was reborn as a witch.
