Mami-san is the strongest magical girl in Mitakihara Town ... she's amazing! And she's really smart and kind, and really pretty, too ... And she always has the best tea at her apartment.

[well okay that last part maybe isn't that amazing. but having tea and cake with Mami-san after a long night of fighting Nightmares is one of Madoka's favorite things in the world.]

She's been a magical girl the longest, so she leads the rest of us.
