Walking through the hallways, Koga and Naze are intercepted by Kumagawa. Naze tells Koga to leave the two of them alone. In Class -13's classroom, Kumagawa invites Naze to join him. Naze initially refuses, but changes her mind after Kumagawa promises to make her the most unfortunate person in the world. Waiting outside Class -13's classroom, the other Minuses discuss Naze. Still in the meeting room, Medaka receives a phone call from Shiranui, telling her that Kumagawa is trying to recruit her sister. She initially decides to leave it up to Naze, but is convinced by Shiranui and Zenkichi to intervene. Naze first takes a look at Class -13's roster, and is impressed by the Minuses Kumagawa has gathered, by one individual in particular. After thinking about the Student Council however, Naze realizes she cannot betray them and makes to leave. She is stopped by Shibushi, who reveals Koga is under attack. Naze begs to Kumagawa to stop, but he hands her his cellphone. Medaka and the others have saved Koga from the attack by Class -13. Medaka asks her sister to remain her ally. Naze agrees to stick with her, and declares she will crush Shibushi. In the face of Naze's anger, Shibushi tells her they can fight in the Secretary's Battle.
