Maybe nemesis is the journalist's daughter who pursued Ayano's mother and tried to expose her for killing her rivals to get her senpai for herself (Ayano's father). So she find it as the best chance and fair to kill Ayano as an act of vengeance towards Ayano's mother and to stop Ayano from ruining other students lives their families like her mother especially that Ayano is becoming the very picture of her mother and she's following her footsteps. Just my theory.
