Mami Tomoe was walking around trying to take her mind off the fact that her magical girl student that Mami was mentoring named Kyoko Sakura had turned into a witch and before Mami could go into her apartment she was knocked out by some sort of magic and saw Kyoko in her human form.

“Sorry Mami..”

Mami then woke up in a child’s bed and looked down and realized that she was in a child form everything was the same and she was a child and she knew it had to do something with Ophelia who was also Kyoko.
