Oriko Mikuni

Oriko Mikuni is the titular character from Puella Magi Oriko Magica. She is a magical girl with the ability to foresee the future.

Oriko's prophetic magic showed her that magical girls can become witches, and because of that, a terrible future could await the city. Due to that vision, as well as her upbringing as the daughter of a politician, Oriko feels responsible to prevent that possible future, at all costs. She feels that her manipulative means are justified by her end goal of protecting the peace she has achieved in her life with Kirika, as well as bringing peace to the world. Oriko also seems to be highly influenced by her political family in her ability to exercise Machiavellian tactics with much personal charisma, all for the sake of a lofty goal.
