When she was about 13 years old, her latent esper abilities began randomly manifesting themselves, causing people to label her a "witch" or a "devil child", and this caused her mother to have to turn to prostitution for money.
She was tricked into believing her mother was going to be killed, which caused her latent esper powers to fully manifest. Because of this, she now works as a scout for Talon, mercilessly hunting down espers such as Lan. Her interaction and blooming friendship with Lan and others at the school, however, has caused her to remember her humanity and she begins to question her loyalties to Talon.

The OVA series has been described as "a visual delight" which "harkens back to a simpler age, when the important thing was that the characters looked cute and the action looked cool", even though the "plot fits together, but only barely". While based on shōjo manga, the series contains intense and graphic violence, which is not typical for most shōjo works. The anime is considered "a little bit better than average, though it "doesn't feel finished", but it is "better than the vast majority of 'magical warrior'" series.
