As Kona becomes intrigued by rumors of Gunvarrel's last episode being leaked, she and Kaito go to solve the conditions for unlocked Kimijima's 3rd report, finding the tasks pretty tedious. As Kaito manages to beat the Kill-Ballad cheater whilst passing the time, Kona gets infected with a virus whilst trying to analyse the data. Later that night, Kaito tries to get information about Kimijima out of Mizuka, whilst Misa is sent by her higher-ups to investigate Kimijima's reports. The next day, after the gang use Kanna to record motions for the GunPro-2, Kaito and Kona manage to unlock the third report, which talks about plans to use a magnetic storm to destroy mankind, mentioning Misa's Exoskeleton company as being part of it. Upon arriving back home, Kona learns that the top three ranked Kill Ballad players had in fact died in their homes half a year ago.

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.

Kaito arrives before Misaki, with the others helping to divert the missiles she fires using AR decoys, although Kaito is forced to use the Slow-Mo and sacrifice one of his pile bunkers to dodge the last one. Kaito manages to get up close to Misaki's Sumeragi and use the Slow-Mo to attack her with the other pile bunker. However, this knocks Misaki out and allows Kimijima to take full control of her as he divides the Sumeragi into a more mobile unit. After locking down the launch sequence, despite Nao and the other adults reclaming the control room, Kimijima launches an attack at the others forcing them to seperate, which leaves the Super Gunbuild-1 with only five minutes of power. Just then, Kona receives a program from Sawada that will erase Kimijima if they can get his avatar in the PokeCom's view, although it requires a reboot which leaves Kaito vulnerable.
