While Isuke contacts her mother, who trained her to become an assassin, Nio meets up with the school's chairman, Yuri, to discuss Class Black's current situation, learning that a typhoon is approaching. Meanwhile, Tokaku and Haru are approached by Shinya, the split personality of Mahiru Banba who appears during the night, leading Tokaku to believe that she will be the next one to target Haru. The next day, as Tokaku wonders what she will do when Class Black is over, she and Haru discover an advance warning, which appears to be from Mahiru/Shinya, and rush back to their dorms. However, they are confronted by Isuke, the real owner of the warning, who injures Tokaku's arm. Tokaku takes Haru to the biology room, telling her to hide there whilst she goes to confront Isuke, who calls Tokaku's bluff that she is actually unable to kill anyone. With Tokaku distracted by her fight against Isuke, Shinya appears before Haru, declaring her intent to kill her.
