You hear a white, cat-like creature calling for your help via telepathy. What are you going to do?

A white, emotionless, cat-like creature approaches you… “Hello, my name is Kyubey.” Kyubey said with his usual stoic, smiling expression. “Would you like to make a contract with me, and become a Magical Girl to fight against evil Witches?” He asked, his tail swaying. “I will grant you one wish in exchange for you to become a Magical girl…” His red eyes stared into your soul. “Anything you desire...” He seemed a bit eerie… Like he was completely emotionless.
