Madoka and Sayaka are getting used to Mami's witch hunting trial course.
Yet their essential wishes remain undecided.
Mami reveals her past to the anxious two girls.
Sayaka asks, "Does the wish have to be for myself?"
Mami warns sternly, "You need to know your wish more clearly if you want to make other people's wishes come true."
One day, they discover a Grief Seed that is ready to hatch in the hospital parking lot.
If they leave the grief seed alone, it could turn into a big disaster. Sayaka and Kyubey stay to guard it while Madoka runs for help to get Mami.
