Oriko Magica Sadness Prayer: Chapter 1
A recently contracted Oriko Mikuni attends Shirome Middle. Kyubey is monitoring her due to her refusal to hunt witches. Nearby, Komaki Asako scolds two students for laughing at Oriko behind her back, rather than to her face like she does. Her tagalongs quickly drag her away before things get too heated. Later, Komaki confronts Oriko about her attitude as of late, eventually causing Oriko to 'snap', for lack of a better word.
Walking somewhere after school, Oriko mulls over her first foresight: The end of the world and the girl who will cause it. She's... conflicted on her moral values. Tuning back into reality, Oriko realizes she walked into a witch's barrier. Fortunately she doesn't even have to transform, as Komaki appears out of nowhere and PWNs the witch, much to Oriko's shock. Yes, Komaki's a magical girl too.
