As it turned out, children were still children.
Once Mami Tomoe learned that the people interrogating her were neither a dark organization nor some evil force, but an official government agency, she immediately wilted. Under Duanmu Huai's questioning, she stammered out everything she knew.
First of all, what is a Magical Girl?
You become a Magical Girl by signing a contract with Kyubey.
Did it grant your wish?
Yes. I was in a car accident at the time, and Kyubey appeared in front of me just like that. It said it wanted to sign a contract with me and grant my wish. I wished that I didn't want to die, and then I survived...
What is this gem?
It's called a Soul Stone. It's created after signing a contract with Kyubey. It's the source of a Magical Girl's power and proof that she is a Magical Girl.
What is that black sphere? What were you doing when you used it to touch the Soul Stone earlier?
That's called a Grief Seed. I don't know the exact details either, but Magical Girls consume magic power when fighting, and when their emotions fluctuate violently, it causes the Soul Stone to become clouded. So they need to use a Grief Seed to absorb the impurities from the Soul Stone and restore its purity.
What happens if the impurities in the Soul Stone aren't removed?
