Kaito and Akiho travel to the Tokyo Expo with their robot, where they discover they have to share a hotel room. As Kaito has nightmares that night, Akiho asks him to be a bit more open with his troubles. Whilst preparing for the expo, Akiho becomes excited when she hears Misaki will be at the expo promoting the Exoskeleton robots. Kaito decides to meet up with her in person in order to confront her about Mizuka's death, also talking about Kimijima, her meeting with the real Airi, who woke up in hospital the other day, and above all, her attitude towards Akiho. The Tokyo Expo soon begins with Akiho having a tough time impressing the crowd with the recent bias against Gunvarrel. Despite Kaito's warnings, Akiho goes to see Misaki, who is seen in a fully robotic suit. Just then Sawada appears and brings out a gun, shooting it when Misaki starts to run away.

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.
