Mikoto and the AntiSkill fight back against the creature but it only causes 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 happen, Harumi explains the creature, called AIM Burst, is the result of the 10,000 Level Upper user's AIM fields and their negative thoughts. With the help of AntiSkill members Aiho Yomikawa and Tsuzuri Tess?, 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 Level Upper user's powers and emits their negative thoughts to Mikoto and Harumi. Mikoto battles AIM Burst again and apologizes to the users for not understanding their feelings and tells them not to give up on their dreams before shooting a railgun to destroy the creature's core. As sunset arrives, a mysterious woman and her team inspect the damages at the power plant while Harumi is arrested by the AntiSkill, still hoping to find a way to cure her students. 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.
