Mikoto attempts to fight the creature, but her attacks only cause it to regenerate its wounds and grow bigger as it heads towards a nuclear power plant. With the network out of control, the comatose Level Upper users starts screaming in pain. Realizing what has happened, Harumi explains how the creature, called AIM Burst, is the result of the 10,000 Level Upper users' AIM fields and their negative thoughts. With the help of AntiSkill members Aiho Yomikawa and Tsuzuri Tesso, Kazari manages to upload the cure Harumi gave her, a song file, which is played all over the city, calming the Level Upper users and weakening AIM Burst. Despite losing its regenerative ability, AIM Burst is still able to use the abilities of the Level Upper victims, emitting their negative thoughts to Mikoto and Harumi. Mikoto battles AIM Burst again and apologizes to the users for not understanding their feelings, telling them not to give up on their dreams before shooting a railgun to destroy the creature's core, defeating it. As sunset arrives and a mysterious woman and her team inspect the damages at the power plant, Harumi is taking into custody by the AntiSkill, still hoping to find a way to cure her students and challenging Mikoto to stop her again if she doesn't agree with her methods. Kazari later meets up with Ruiko who, having recovered from her coma and lost her powers, apologizes to her for forgetting what was truly important.
