Mami is a veteran magical girl and a third-year student at Madoka's school. She lives alone in a penthouse after the death of her parents in a car accident, one which she was able to survive only due to contracting with Kyubey to save her own life.
Mami is particularly focused on saving those around her, with a traditionally selfless perspective on the role of magical girl, and has a habit of giving names to her finishing attacks. Though her outward disposition is cheery and confident, Mami feels deeply alone as she has no friends to confide in or support her as she fights. Due to her desire to save as many people as she can, Mami tends to clash with other Puella Magi who would rather wait for witches to "mature" in order to obtain Grief Seeds, despite that resulting in human casualties.
