Editing The Broken Universe:Kei (section)

=Crisis: Expelled from her old school=
Kei used to be one of the star members of Nayamigawa High's martial arts club, despite only being a first-year student there. Despite her skill and popularity among the student body, however, she had been reprimanded more than once for her hot-headed attitude when it got her into trouble.

Not long after she became a mahou shoujo, she had to leave practice early to find a daemon she thought was getting dangerously close to the school. By the time she arrived, the damage had already been done, the daemon had moved on...and the students that had come to investigate thought they recognized Kei.

Although Kei was able to escape before anyone truly recognized her, news traveled fast among the Nayamigawa student body, and she became the subject of vicious rumors, ranging from her being part of a girl gang, to her having planned to blow up the school. The rash of daemon attacks certainly didn't help either; she got blamed for many of them, which frustrated her to no end because she couldn't prove she wasn't responsible. It didn't take long for her to flip out and assault one of her classmates, and when the administration found out, they expelled Kei on the spot. Fortunately for her, she was able to transfer to another school relatively quickly, but that didn't stop the rumors from following her...
