• Duke advised Lucky Right Hand to pat the nun on the shoulder, and the poster stopped updating after agreeing to follow the advice.

Duke tracked the escalating AIM Burst incidents while keeping Misaka 9800 away from Kamijou Touma. Kuroko and Misaka Mikoto identified Kiyama Harumi as the likely mastermind, but Uiharu Kazari had gone to meet her, and Konori Mii's call to Kiyama's institute was answered by Duke.

• Duke failed to break into The Bank, exchanged messages with Kamijou Touma through Misaka 9800, and warned her to stay away from him.

• Misaka Mikoto defeated Kiyama Harumi and read her memories, but still told her she could not justify hurting others to save the children.
• Kiyama Harumi lost control of the network and collapsed as a grotesque infant-like monster emerged and grew to more than ten meters tall.

Kiyama Harumi gave Misaka Mikoto the AIM Burst treatment program as a possible way to stop the AIM Beast, while the monster grew stronger under the security officers’ attack. Duke protected Kiyama and the officers from the Beast’s counterattack by summoning a dragon-shaped ice barrier.

• Kamijou and Stiyl watched the destructive fight from a distance, and Stiyl worried that Kanzaki Kaori was struggling against Duke.
• Kanzaki realized Duke could repeatedly disrupt her sword techniques and that maintaining God Breaker was pushing her body toward collapse.
• Kanzaki retreated, retrieved her scabbard, and prepared her final Battōjutsu strike, admitting she would use magic because she could not afford to lose.
• Duke sheathed his sword, gathered his Sword Intent, and called out the Unseen Divine Wind Style: White Tiger as Kanzaki began Only Flash.
