You are an average 14 year old girl living in Mitakihara City, turned Magical Girl through a contract with a mysterious creature called Kyubey. Shortly after, you met Mami Tomoe, a nice and friendly girl around your age who is also a Magical Girl, and Bebe, Mami's weird pet(?). You're hanging out with Mami at her home, doing homework and chatting, when Bebe tugs on your sleeve.

Bebe: Cheese! Cheese!

Mami: Bebe, stop bothering her!
