As the robots continue to run rampant in Tokyo, Kona explains to Kaito that the login to their control panel has been altered by the hackers to require they defeat a Kill-Ballad CPU opponent. Struggling to beat the opponent, Kaito decides to try and force his slow-mo by pushing his body to its limits, but to no avail. Kona soon founds out the person behind the hack was one of the members from her development circle, Maguyan, who claims he was forced to do it as his family was taken hostage. Kaito soon realises that Maguyan has in fact been brainwashed. As Kona hears the support of her friends from the Robotics Club, she explains how she created Kill-Ballad to keep Gunvarrel, and her mother's memories, alive. As the police show at Kona's doorstep, Akiho, Junna and Subaru help lure them away, buying Kaito and Kona some time to beat the Kill-Ballad opponent.

As solar flares start affecting computers, people besides Kaito and his group become able to see Airi, who has begun acting weird lately. A planned maintenance on the Iro-O system that could potentially erase Airi means that Kaito needs to fulfill the conditions for the sixth report before Christmas Eve. After Kaito unlocks the sixth report, Airi states that she wants to go to Kimijima's house for her birthday on Christmas Eve. There, Kaito discovers a machine in his basement containing Airi's original human body. Airi explains how she was cursed with an incurable affliction and always spent her days bedridden, hoping for a White Christmas. She soon met Kimijima, who let her see the world through the Iro-O system. As Airi's condition worsened, Kimijima put Airi into a deep sleep in order to wait for a cure and created the program Airi to keep her company.
